How does your organisation allocate capacity for production workloads in the cloud?
Peak Provisioning: Capacity is typically provisioned based on peak usage estimates, potentially leading to underutilisation during off-peak times.
How to determine if this good enough
When an organisation provisions capacity solely based on the highest possible load (peak usage), it generally results in:
High Reliance on Worst-Case Scenarios
- You assume your daily or seasonal peak might occur at any time, so you allocate enough VMs, containers, or resources to handle that load continuously.
- This can be seen as “good enough” if your traffic is extremely spiky, mission-critical, or your downtime tolerance is near zero.
Predictable But Potentially Wasteful Costs
- By maintaining peak capacity around the clock, your spend is predictable, but you may overpay substantially during off-peak hours.
- This might be acceptable if your budget is not severely constrained or if your leadership prioritises simplicity over optimisation.
Minimal Operational Complexity
- No advanced autoscaling or reconfiguration scripts are needed, as you do not scale up or down dynamically.
- For teams with limited cloud or DevOps expertise, “peak provisioning” might be temporarily “good enough.”
Compliance or Regulatory Factors
- Certain government services may face strict requirements that demand consistent capacity. If scaling or re-provisioning poses risk to meeting an SLA, you may choose to keep peak capacity as a safer option.
You might find “Peak Provisioning” still acceptable if cost oversight is low, your risk threshold is minimal, and you prefer operational simplicity. However, with public sector budgets under increasing scrutiny and user load patterns often varying significantly, this approach often wastes resources—both financial and environmental.
How to do better
Below are rapidly actionable steps to reduce waste and move beyond provisioning for the extreme peak:
Implement Resource Monitoring and Basic Analytics
- Gather usage metrics to understand actual peaks, off-peak times, and daily/weekly cycles:
- AWS CloudWatch metrics + AWS Cost Explorer to see usage vs. cost patterns
- Azure Monitor + Azure Cost Management for hourly/daily usage trends
- GCP Monitoring + GCP Billing reports (BigQuery export for deeper analysis)
- OCI Monitoring + OCI Cost Analysis for instance-level metrics
- Share this data with stakeholders to highlight the discrepancy between peak vs. average usage.
- Gather usage metrics to understand actual peaks, off-peak times, and daily/weekly cycles:
Pilot Scheduled Shutdowns for Non-Critical Systems
- Identify development and testing environments or batch-processing servers that don’t require 24/7 availability:
- Utilise AWS Instance Scheduler to automate start and stop times for Amazon EC2 and RDS instances.
- Implement Azure Automation’s Start/Stop VMs v2 to manage virtual machines on user-defined schedules.
- Apply Google Cloud’s Instance Schedules to automatically start and stop Compute Engine instances based on a schedule.
- Use Oracle Cloud Infrastructure’s Resource Scheduler to manage compute instances’ power states according to defined schedules.
- Sharing this data with stakeholders can highlight the discrepancy between peak and average usage, demonstrating immediate cost savings without impacting production systems.
- Identify development and testing environments or batch-processing servers that don’t require 24/7 availability:
Explore Simple Autoscaling Solutions
Even if you continue peak provisioning for mission-critical workloads, consider selecting a smaller or non-critical service to test autoscaling:
AWS Auto Scaling Groups – basic CPU-based triggers: Amazon EC2 Auto Scaling allows you to automatically add or remove EC2 instances based on CPU utilisation or other metrics, ensuring your application scales to meet demand.
Azure Virtual Machine Scale Sets – scale by CPU or memory usage: Azure Virtual Machine Scale Sets enable you to create and manage a group of load-balanced VMs, automatically scaling the number of instances based on CPU or memory usage to match your workload demands.
GCP Managed Instance Groups – autoscale based on utilisation thresholds: Google Cloud’s Managed Instance Groups provide autoscaling capabilities that adjust the number of VM instances based on utilsation metrics, such as CPU usage, to accommodate changing workloads.
OCI Instance Pool Autoscaling – CPU or custom metrics triggers: Oracle Cloud Infrastructure’s Instance Pool Autoscaling allows you to automatically adjust the number of instances in a pool based on CPU utilisation or custom metrics, helping to optimise performance and cost.
Implementing autoscaling in a controlled environment allows you to evaluate its benefits and challenges, providing valuable insights before considering broader adoption for more critical workloads.
Review Reserved or Discounted Pricing
If you must maintain consistently high capacity, consider vendor discount programs to reduce per-hour costs:
AWS Savings Plans or Reserved Instances: AWS offers Savings Plans, which provide flexibility by allowing you to commit to a consistent amount of compute usage (measured in $/hour) over a 1- or 3-year term, applicable across various services and regions. Reserved Instances, on the other hand, involve committing to specific instance configurations for a term, offering significant discounts for predictable workloads.
Azure Reservations for VMs and Reserved Capacity: Azure provides Reservations that allow you to commit to a specific VM or database service for a 1- or 3-year period, resulting in cost savings compared to pay-as-you-go pricing. These reservations are ideal for workloads with predictable resource requirements.
GCP Committed Use Discounts: Google Cloud offers Committed Use Discounts, enabling you to commit to a certain amount of usage for a 1- or 3-year term, which can lead to substantial savings for steady-state or predictable workloads.
OCI Universal Credits: Oracle Cloud Infrastructure provides Universal Credits, allowing you to utilise any OCI platform service in any region with a flexible consumption model. By purchasing a sufficient number of credits, you can benefit from volume discounts and predictable billing, which is advantageous for maintaining high-capacity workloads.
Implementing these discount programs won’t eliminate over-provisioning but can soften the budget impact.
Engage Leadership on the Financial and Sustainability Benefits
- Present how on-demand autoscaling or even basic scheduling can reduce overhead and potentially improve your service’s environmental footprint.
- Link these improvements to departmental net-zero or cost reduction goals, highlighting easy wins.
Through monitoring, scheduling, basic autoscaling pilots, and potential reserved capacity, you can move away from static peak provisioning. This approach preserves reliability while unlocking efficiency gains—an important step in balancing cost, compliance, and performance goals in the UK public sector.
Manual Scaling Based on Average Consumption: Capacity is provisioned for average usage, with manual scaling adjustments made seasonally or as needed.
How to determine if this good enough
This stage represents an improvement over peak provisioning: you size your environment around typical usage rather than the maximum. You might see this as “good enough” if:
Periodic But Manageable Traffic Patterns
- You may only observe seasonal spikes (e.g., monthly end-of-period reporting, yearly enrollments, etc.). Manually scaling before known events could be sufficient.
- The overhead of full autoscaling might not seem worthwhile if spikes are infrequent and predictable.
Comfortable Manual Operations
- You have a change-management process that can quickly add or remove capacity on a known schedule (e.g., scaling up ahead of local council tax billing cycles).
- If your staff can handle these tasks promptly, the organisation might see no urgency in adopting automated approaches.
Budgets and Costs Partially Optimised
- By aligning capacity to average usage (rather than peak), you reduce some waste. You might see moderate cost savings compared to peak provisioning.
- The cost overhead from less frequent or smaller over-provisioning might be tolerable.
Stable or Slow-Growing Environments
- If your cloud usage is not rapidly increasing, a manual approach might not yet lead to major inefficiencies.
- You have limited real-time or unpredictable usage surges.
That said, manual scaling can become a bottleneck if usage unexpectedly grows or if multiple applications need frequent changes. The risk is human error (forgetting to scale back down), delayed response to traffic spikes, or missed budget opportunities.
How to do better
Here are rapidly actionable steps to evolve from manual seasonal scaling to a more automated, responsive model:
Automate the Manual Steps You Already Do
If you anticipate seasonal peaks (e.g., quarterly public reporting load), replace manual processes with scheduled scripts to ensure timely scaling and prevent missed scale-downs:
AWS: Utilise AWS Step Functions in conjunction with Amazon EventBridge Scheduler to automate the start and stop of EC2 instances based on a defined schedule.
Azure: Implement Azure Automation Runbooks within Automation Accounts to create scripts that manage the scaling of resources during peak periods.
Google Cloud Platform (GCP): Leverage Cloud Scheduler to trigger Cloud Functions or Terraform scripts that adjust instance groups in response to anticipated load changes.
Oracle Cloud Infrastructure (OCI): Use Resource Manager stacks combined with Cron tasks to schedule scaling events, ensuring resources are appropriately managed during peak times.
Automating these processes ensures that scaling actions occur as planned, reducing the risk of human error and optimising resource utilisation during peak and off-peak periods.
Identify and Enforce “Scale-Back” Windows
- Even if you scale up for busy times, ensure you have a defined “sunset” for increased capacity:
- Configure an autoscaling group or scale set to revert to default size after the peak.
- Set reminders or triggers to ensure you don’t pay for extra capacity indefinitely.
- Even if you scale up for busy times, ensure you have a defined “sunset” for increased capacity:
Introduce Autoscaling on a Limited Component
Choose a module that frequently experiences load variations within a day or week—perhaps a web front-end for a public information portal:
AWS: Implement Auto Scaling Groups with CPU-based or request-based triggers to automatically adjust the number of EC2 instances handling your service’s load.
Azure: Utilise Virtual Machine Scale Sets or the AKS Cluster Autoscaler to manage the scaling of virtual machines or Kubernetes clusters for your busiest microservices.
Google Cloud Platform (GCP): Use Managed Instance Groups with load-based autoscaling to dynamically adjust the number of instances serving your front-end application based on real-time demand.
Oracle Cloud Infrastructure (OCI): Apply Instance Pool Autoscaling or the OKE Cluster Autoscaler to automatically scale a specific containerised service in response to workload changes.
Implementing autoscaling on a targeted component allows you to observe immediate benefits, such as improved resource utilisation and cost efficiency, which can encourage broader adoption across your infrastructure.
Consider Serverless for Spiky Components
If certain tasks run sporadically (e.g., monthly data transformation or PDF generation), investigate moving them to event-driven or serverless solutions:
AWS: Utilise AWS Lambda for event-driven functions or AWS Fargate for running containers without managing servers. AWS Lambda is ideal for short-duration, event-driven tasks, while AWS Fargate is better suited for longer-running applications and tasks requiring intricate orchestration.
Azure: Implement Azure Functions for serverless compute, Logic Apps for workflow automation, or Container Apps for running microservices and containerised applications. Azure Logic Apps can automate workflows and business processes, making them suitable for scheduled tasks.
Google Cloud Platform (GCP): Deploy Cloud Functions for lightweight event-driven functions or Cloud Run for running containerised applications in a fully managed environment. Cloud Run is suitable for web-based workloads, REST or gRPC APIs, and internal custom back-office apps.
Oracle Cloud Infrastructure (OCI): Use OCI Functions for on-demand, serverless workloads. OCI Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform built on enterprise-grade infrastructure.
Transitioning to serverless solutions for sporadic tasks eliminates the need to manually adjust virtual machines for short bursts, enhancing efficiency and reducing operational overhead.
Monitor and Alert on Usage Deviations
Utilise cost and performance alerts to detect unexpected surges or prolonged idle resources:
AWS: Implement AWS Budgets to set custom cost and usage thresholds, receiving alerts when limits are approached or exceeded. Additionally, use Amazon CloudWatch’s anomaly detection to monitor metrics and identify unusual patterns in resource utilisation.
Azure: Set up Azure Monitor alerts to track resource performance and configure cost anomaly alerts within Azure Cost Management to detect and notify you of unexpected spending patterns.
Google Cloud Platform (GCP): Create budgets in Google Cloud Billing and configure Pub/Sub notifications to receive alerts on cost anomalies, enabling prompt responses to unexpected expenses.
Oracle Cloud Infrastructure (OCI): Establish budgets and set up alert rules in OCI Cost Management to monitor spending. Additionally, configure OCI Alarms with notifications to detect and respond to unusual resource usage patterns.
Implementing these alerts enables quicker responses to anomalies, reducing the reliance on manual monitoring and helping to maintain optimal resource utilisation and cost efficiency.
By automating your manual scaling processes, exploring partial autoscaling, and shifting spiky tasks to serverless, you unlock more agility and cost efficiency. This approach helps ensure you’re not left scrambling if usage deviates from seasonal patterns.
Basic Autoscaling for Certain Components: Autoscaling is enabled for some cloud components, primarily based on simple capacity or utilisation metrics.
How to determine if this good enough
At this stage, you’ve moved beyond purely manual methods: some of your workloads automatically scale in or out when CPU, memory, or queue depth crosses a threshold. This can be “good enough” if:
Limited Service Scope
- You have identified a few critical or high-variance components (e.g., your front-end web tier) that benefit significantly from autoscaling.
- Remaining workloads may be stable or less likely to see large traffic swings.
Simplicity Over Complexity
- You deliberately keep autoscaling rules straightforward (e.g., CPU > 70% for 5 minutes) to avoid over-engineering.
- This might meet departmental objectives, provided the load pattern doesn’t vary unpredictably.
Reduced Manual Overhead
- Thanks to autoscaling on certain components, you rarely intervene during typical usage spikes.
- You still handle major events or seasonal shifts manually, but day-to-day usage is more stable.
Partially Controlled Costs
- Because your most dynamic workloads scale automatically, you see fewer cost overruns from over-provisioning.
- You still might maintain some underutilised capacity for other components, but it’s acceptable given your risk appetite.
If your environment only sees moderate changes in demand and leadership doesn’t demand full elasticity, “Basic Autoscaling for Certain Components” can suffice. However, if your user base or usage patterns expand, or if you aim for deeper cost optimisation, you could unify autoscaling across more workloads and utilise advanced triggers.
How to do better
Below are actionable ways to upgrade from basic autoscaling:
Broaden Autoscaling Coverage
Extend autoscaling to more workloads to enhance efficiency and responsiveness:
AWS:
- EC2 Auto Scaling: Implement EC2 Auto Scaling across multiple groups to automatically adjust the number of EC2 instances based on demand, ensuring consistent application performance.
- ECS Service Auto Scaling: Configure Amazon ECS Service Auto Scaling to automatically scale your containerised services in response to changing demand.

- Cloud SQL Autoscaling: Leverage Cloud SQL’s automatic storage increase to handle growing database storage needs without manual intervention.
Oracle Cloud Infrastructure (OCI):
- Instance Pool Autoscaling: Apply OCI Instance Pool Autoscaling to additional workloads, enabling automatic adjustment of compute resources based on performance metrics.
- Database Auto Scaling: Utilise OCI Autonomous Database Auto Scaling to automatically scale compute and storage resources in response to workload demands.
Gradually incorporating more of your application’s microservices into the autoscaling framework can lead to improved performance, cost efficiency, and resilience across your infrastructure.
Incorporate More Granular Metrics
Move beyond simple CPU-based thresholds to handle memory usage, disk I/O, or application-level concurrency:
AWS: Implement Amazon CloudWatch custom metrics to monitor specific parameters such as memory usage, disk I/O, or application-level metrics. Additionally, utilise Application Load Balancer (ALB) request count to trigger autoscaling based on incoming traffic.
Azure: Use Azure Monitor custom metrics to track specific performance indicators like queue length or HTTP request rate. These metrics can feed into Virtual Machine Scale Sets or the Azure Kubernetes Service (AKS) Horisontal Pod Autoscaler (HPA) for more responsive scaling.
Google Cloud Platform (GCP): Leverage Google Cloud’s Monitoring custom metrics to capture detailed performance data. Implement request-based autoscaling in Google Kubernetes Engine (GKE) or Cloud Run to adjust resources based on real-time demand.
Oracle Cloud Infrastructure (OCI): Utilise OCI Monitoring service’s custom metrics to track parameters such as queue depth, memory usage, or user concurrency. These metrics can inform autoscaling decisions to ensure optimal performance.
Incorporating more granular metrics allows for precise autoscaling, ensuring that resources are allocated based on comprehensive performance indicators rather than relying solely on CPU usage.
Implement Dynamic, Scheduled, or Predictive Scaling
If you observe consistent patterns in your application’s usage—such as increased activity during lunchtime or reduced traffic on weekends—consider enhancing your existing autoscaling strategies with scheduled scaling actions:
AWS: Configure Amazon EC2 Auto Scaling scheduled actions to adjust capacity at predetermined times. For instance, you can set the system to scale up at 08:00 and scale down at 20:00 to align with daily usage patterns.
Azure: Utilise Azure Virtual Machine Scale Sets to implement scheduled scaling. Additionally, integrate scaling adjustments into your Azure DevOps pipelines to automate capacity changes in response to anticipated workload variations.
Google Cloud Platform (GCP): Employ Managed Instance Group (MIG) scheduled scaling to define scaling behaviors based on time-based schedules. Alternatively, use Cloud Scheduler to trigger scripts that adjust resources in line with expected demand fluctuations.
Oracle Cloud Infrastructure (OCI): Set up scheduled autoscaling for instance pools to manage resource allocation according to known usage patterns. You can also deploy Oracle Functions to execute timed scaling events, ensuring resources are appropriately scaled during peak and off-peak periods.
Implementing scheduled scaling allows your system to proactively adjust resources in anticipation of predictable workload changes, enhancing performance and cost efficiency.
For environments with variable and unpredictable workloads, consider utilising predictive scaling features. Predictive scaling analyzes historical data to forecast future demand, enabling the system to scale resources in advance of anticipated spikes. This approach combines the benefits of both proactive and reactive scaling, ensuring optimal resource availability and responsiveness.
AWS: Explore Predictive Scaling for Amazon EC2 Auto Scaling, which uses machine learning models to forecast traffic patterns and adjust capacity accordingly.
Azure: While Azure does not currently offer a native predictive scaling feature, you can implement custom solutions by analyzing historical metrics through Azure Monitor and creating automation scripts to adjust scaling based on predicted trends.
GCP: Google Cloud’s autoscaler primarily operates on real-time metrics. For predictive capabilities, consider developing custom predictive models using historical data from Cloud Monitoring to inform scaling decisions.
OCI: Oracle Cloud Infrastructure allows for the creation of custom scripts and functions to implement predictive scaling based on historical usage patterns, although a native predictive scaling feature may not be available.
By integrating scheduled and predictive scaling strategies, you can enhance your application’s ability to handle varying workloads efficiently, ensuring optimal performance while managing costs effectively.
Enhance Observability to Validate Autoscaling Efficacy
Instrument your autoscaling events and track them to ensure optimal performance and resource utilisation:
Dashboard Real-Time Metrics: Monitor CPU, memory, and queue metrics alongside scaling events to visualise system performance in real-time.
Analyze Scaling Timeliness: Assess whether scaling actions occur promptly by checking for prolonged high CPU usage or frequent scale-in events that may indicate over-scaling.
Tools:
AWS:
AWS X-Ray: Utilise AWS X-Ray to trace requests through your application, gaining insights into performance bottlenecks and the impact of scaling events.
Amazon CloudWatch: Create dashboards in Amazon CloudWatch to display real-time metrics and logs, correlating them with scaling activities for comprehensive monitoring.

Oracle Cloud Infrastructure (OCI):
OCI Logging: Use OCI Logging to manage and search logs, providing visibility into scaling events and their effects on system performance.
OCI Monitoring: Utilise OCI Monitoring to track metrics and set alarms, ensuring that scaling actions align with performance expectations.
By enhancing observability, you can validate the effectiveness of your autoscaling strategies, promptly identify and address issues, and optimise resource allocation to maintain application performance and cost efficiency.
Adopt Spot/Preemptible Instances for Autoscaled Non-Critical Workloads
To further optimise costs, consider utilising spot or preemptible virtual machines (VMs) for non-critical, autoscaled workloads. These instances are offered at significant discounts compared to standard on-demand instances but can be terminated by the cloud provider when resources are needed elsewhere. Therefore, they are best suited for fault-tolerant and flexible applications.
AWS: Implement EC2 Spot Instances within an Auto Scaling Group to run fault-tolerant workloads at up to 90% off the On-Demand price. By configuring Auto Scaling groups with mixed instances, you can combine Spot Instances with On-Demand Instances to balance cost and availability.
Azure: Utilise Azure Spot Virtual Machines within Virtual Machine Scale Sets for non-critical workloads. Azure Spot VMs allow you to take advantage of unused capacity at significant cost savings, making them ideal for interruptible workloads such as batch processing jobs and development/testing environments.
Google Cloud Platform (GCP): Deploy Preemptible VMs in Managed Instance Groups to run short-duration, fault-tolerant workloads at a reduced cost. Preemptible VMs provide substantial savings for workloads that can tolerate interruptions, such as data analysis and batch processing tasks.
Oracle Cloud Infrastructure (OCI): Leverage Preemptible Instances for batch processing or flexible tasks. OCI Preemptible Instances offer a cost-effective solution for workloads that are resilient to interruptions, enabling efficient scaling of non-critical applications.
By integrating these cost-effective instance types into your autoscaling strategies, you can significantly reduce expenses for non-critical workloads while maintaining the flexibility to scale resources as needed.
By broadening autoscaling across more components, incorporating richer metrics, scheduling, and advanced cost strategies like spot instances, you transform your “basic” scaling approach into a more agile, cost-effective solution. Over time, these steps foster robust, automated resource management across your entire environment.
Widespread Autoscaling with Basic Metrics: Autoscaling is a common practice, although it mainly utilises basic metrics, with limited use of log or application-specific metrics.
How to determine if this good enough
You’ve expanded autoscaling across many workloads: from front-end services to internal APIs, possibly including some data processing components. However, you’re mostly using CPU, memory, or standard throughput metrics as triggers. This can be “good enough” if:
Comprehensive Coverage
- Most of your core applications scale automatically as demand changes. Manual interventions are rare and usually revolve around unusual events or big product launches.
Efficient Day-to-Day Operations
- Cost and capacity usage are largely optimised since few resources remain significantly underutilised or idle.
- Staff seldom worry about reconfiguring capacity for typical fluctuations.
Satisfactory Performance
- Using basic metrics (CPU, memory) covers typical load patterns adequately.
- The risk of slower scale-up in more complex scenarios (like surges in queue lengths or specific user transactions) might be acceptable.
Stable or Predictable Load Growth
- Even with widespread autoscaling, if your usage grows in somewhat predictable increments, basic triggers might suffice.
- You rarely need to investigate advanced logs or correlation with end-user response times to refine scaling.
If your service-level objectives (SLOs) and budgets remain met with these simpler triggers, you may be comfortable. However, more advanced autoscaling can yield better responsiveness for spiky or complex applications that rely heavily on queue lengths, user concurrency, or custom application metrics (e.g., transactions per second, memory leaks, etc.).
How to do better
Here are actionable ways to refine your widespread autoscaling strategy to handle more nuanced workloads:
Adopt Application-Level or Log-Based Metrics
Move beyond CPU and memory metrics to incorporate transaction rates, request latency, or user concurrency for more responsive and efficient autoscaling:
AWS:
- CloudWatch Custom Metrics: Publish custom metrics derived from application logs to Amazon CloudWatch, enabling monitoring of specific application-level indicators such as transaction rates and user concurrency.
- Real-Time Log Analysis with Kinesis and Lambda: Set up real-time log analysis by streaming logs through Amazon Kinesis and processing them with AWS Lambda to generate dynamic scaling triggers based on application behavior.
Azure:
- Application Insights: Utilise Azure Monitor’s Application Insights to collect detailed usage data, including request rates and response times, which can inform scaling decisions for services hosted in Azure Kubernetes Service (AKS) or Virtual Machine Scale Sets.
- Custom Logs for Scaling Signals: Implement custom logging to capture specific application metrics and configure Azure Monitor to use these logs as signals for autoscaling, enhancing responsiveness to real-time application demands.
Google Cloud Platform (GCP):
- Cloud Monitoring Custom Metrics: Create custom metrics in Google Cloud’s Monitoring to track application-specific indicators such as request count, latency, or queue depth, facilitating more precise autoscaling of Compute Engine (GCE) instances or Google Kubernetes Engine (GKE) clusters.
- Integration with Logging: Combine Cloud Logging with Cloud Monitoring to analyze application logs and derive metrics that can trigger autoscaling events based on real-time application performance.
Oracle Cloud Infrastructure (OCI):
- Monitoring Custom Metrics: Leverage OCI Monitoring to create custom metrics from application logs, capturing detailed performance indicators that can inform autoscaling decisions.
- Logging Analytics: Use OCI Logging Analytics to process and analyze application logs, extracting metrics that reflect user concurrency or transaction rates, which can then be used to trigger autoscaling events.
Incorporating application-level and log-based metrics into your autoscaling strategy allows for more nuanced and effective scaling decisions, ensuring that resources align closely with actual application demands and improving overall performance and cost efficiency.
Introduce Multi-Metric Policies
- Instead of a single threshold, combine metrics. For instance:
- Scale up if CPU > 70% AND average request latency > 300ms.
- This ensures you only scale when both resource utilisation and user experience degrade, reducing false positives or unneeded expansions.
- Instead of a single threshold, combine metrics. For instance:
Implement Predictive or Machine Learning–Driven Autoscaling
To anticipate demand spikes before traditional metrics like CPU utilisation react, consider implementing predictive or machine learning–driven autoscaling solutions offered by cloud providers:
AWS:
- Predictive Scaling: Leverage Predictive Scaling for Amazon EC2 Auto Scaling, which analyzes historical data to forecast future traffic and proactively adjusts capacity to meet anticipated demand.
Azure:
- Predictive Autoscale: Utilise Predictive Autoscale in Azure Monitor, which employs machine learning to forecast CPU load for Virtual Machine Scale Sets based on historical usage patterns, enabling proactive scaling.
Google Cloud Platform (GCP):
- Custom Machine Learning Models: Develop custom machine learning models to analyze historical performance data and predict future demand, triggering autoscaling events in services like Google Kubernetes Engine (GKE) or Cloud Run based on these forecasts.
Oracle Cloud Infrastructure (OCI):
- Custom Analytics Integration: Integrate Oracle Analytics Cloud with OCI to perform machine learning–based forecasting, enabling predictive scaling by analyzing historical data and anticipating future resource requirements.
Implementing predictive or machine learning–driven autoscaling allows your applications to adjust resources proactively, maintaining performance and cost efficiency by anticipating demand before traditional metrics indicate the need for scaling.
Correlate Autoscaling with End-User Experience
To enhance user satisfaction, align your autoscaling strategies with user-centric metrics such as page load times and overall responsiveness. By monitoring these metrics, you can ensure that scaling actions directly improve the end-user experience.
AWS:
- Application Load Balancer (ALB) Target Response Times: Monitor ALB target response times using Amazon CloudWatch to assess backend performance. Elevated response times can indicate the need for scaling to maintain optimal user experience.
- Network Load Balancer (NLB) Metrics: Track NLB metrics to monitor network performance and identify potential bottlenecks affecting end-user experience.
Azure:
- Azure Front Door Logs: Analyze Azure Front Door logs to monitor end-to-end latency and other performance metrics. Insights from these logs can inform scaling decisions to enhance user experience.

Oracle Cloud Infrastructure (OCI):
- Load Balancer Health Checks: Implement OCI Load Balancer health checks to monitor backend server performance. Use health check data to inform autoscaling decisions that directly impact user experience.
- Custom Application Pings: Set up custom application pings to measure response times and user concurrency, feeding this data into autoscaling triggers to maintain optimal performance during varying user loads.
By integrating user-centric metrics into your autoscaling logic, you ensure that scaling actions are directly correlated with improvements in end-user experience, leading to higher satisfaction and engagement.
Refine Scaling Cooldowns and Timers
- Tweak scale-up and scale-down intervals to avoid thrashing:
- A short scale-up delay can address spikes quickly.
- A slightly longer scale-down delay prevents abrupt resource removals when a short spike recedes.
- Evaluate your autoscaling policy settings monthly to align with evolving traffic patterns.
- Tweak scale-up and scale-down intervals to avoid thrashing:
By incorporating more sophisticated application or log-based metrics, predictive scaling, and user-centric triggers, you ensure capacity aligns closely with real workloads. This approach elevates your autoscaling from a broad CPU/memory-based strategy to a finely tuned system that balances user experience, performance, and cost efficiency.
Advanced Autoscaling Using Detailed Metrics: Autoscaling is ubiquitously used, based on sophisticated log or application metrics, allowing for highly responsive and efficient capacity allocation.
How to determine if this good enough
In this final, most mature stage, your organisation applies advanced autoscaling across practically every production workload. Detailed logs, queue depths, user concurrency, or response times drive scaling decisions. This likely means:
Holistic Observability and Telemetry
- You collect and analyze logs, metrics, and traces in near real-time, correlating them to auto-scale events.
- Teams have dashboards that reflect business-level metrics (e.g., transactions processed, citizen requests served) to trigger expansions or contractions.
Proactive or Predictive Scaling
- You anticipate traffic spikes based on historical data or usage trends (like major public announcements, election result postings, etc.).
- Scale actions happen before a noticeable performance drop, offering a seamless user experience.
Minimal Human Intervention
- Manual resizing is rare, reserved for extraordinary circumstances (e.g., emergent security patches, new application deployments).
- Staff focus on refining autoscaling policies, not reacting to capacity emergencies.
Cost-Optimised and Performance-Savvy
- Because you rarely over-provision for extended periods, your budget usage remains tightly aligned with actual needs.
- End-users or citizens experience consistently fast response times due to prompt scale-outs.
If you find that your applications handle usage spikes gracefully, cost anomalies are rare, and advanced metrics keep everything stable, you have likely achieved an advanced autoscaling posture. Nevertheless, with the rapid evolution of cloud services, there are always methods to iterate and improve.
How to do better
Even at the top level, you can refine and push boundaries further:
Adopt More Granular “Distributed SLO” Metrics
Evaluate Each Microservice’s Service-Level Objectives (SLOs): Define precise SLOs for each microservice, such as ensuring the 99th-percentile latency remains under 400 milliseconds. This granular approach allows for targeted performance monitoring and scaling decisions.
Utilise Cloud Provider Tools to Monitor and Enforce SLOs:
AWS:
- CloudWatch ServiceLens: Integrate Amazon CloudWatch ServiceLens to gain comprehensive insights into application performance and availability, correlating metrics, logs, and traces.
- Custom Metrics and SLO-Based Alerts: Implement custom CloudWatch metrics to monitor specific performance indicators and set up SLO-based alerts to proactively manage service health.
Azure:
- Application Insights: Leverage Azure Monitor’s Application Insights to track detailed telemetry data, enabling the definition and monitoring of SLOs for individual microservices.
- Service Map: Use Azure Monitor’s Service Map to visualise dependencies and performance metrics across services, aiding in the assessment of SLO adherence.
Google Cloud Platform (GCP):
- Cloud Operations Suite: Employ Google Cloud’s Operations Suite to create SLO dashboards that monitor service performance against defined objectives, facilitating informed scaling decisions.
Oracle Cloud Infrastructure (OCI):
- Observability and Management Platform: Implement OCI’s observability tools to define SLOs and correlate them with performance metrics, ensuring each microservice meets its performance targets.
Benefits of Implementing Distributed SLO Metrics:
Precision in Scaling: By closely monitoring how each component meets its SLOs, you can make informed decisions to scale resources appropriately, balancing performance needs with cost considerations.
Proactive Issue Detection: Granular SLO metrics enable the early detection of performance degradations within specific microservices, allowing for timely interventions before they impact the overall system.
Enhanced User Experience: Maintaining stringent SLOs ensures that end-users receive consistent and reliable service, thereby improving satisfaction and trust in your application.
Implementation Considerations:
Define Clear SLOs: Collaborate with stakeholders to establish realistic and measurable SLOs for each microservice, considering factors such as latency, throughput, and error rates.
Continuous Monitoring and Adjustment: Regularly review and adjust SLOs and associated monitoring tools to adapt to evolving application requirements and user expectations.
Conclusion: Adopting more granular “distributed SLO” metrics empowers you to fine-tune your application’s performance management, ensuring that each microservice operates within its defined parameters. This approach facilitates precise scaling decisions, optimising both performance and cost efficiency.
Experiment with Multi-Provider or Hybrid Autoscaling
- If policy allows, or your architecture is containerised, test the feasibility of bursting into another region or cloud for capacity:
- This approach is advanced but can further optimise resilience and cost across providers.
Integrate with Detailed Cost Allocation & Forecasting
- Combine real-time scale data with cost forecasting models:
- AWS Budgets with advanced forecasting, or AWS Cost Anomaly Detection for unplanned scale-ups.
- Azure Cost Management budgets with Power BI integration for detailed analysis.
- GCP Budgets & cost predictions in the Billing console, with BigQuery analysis for scale patterns vs. spend.
- OCI Cost Analysis with usage forecasting and custom alerts for spike detection.
- This ensures you can quickly investigate if an unusual surge in scaling leads to unapproved budget expansions.
- Combine real-time scale data with cost forecasting models:

How does your organisation approach the use of compute services in the cloud?
Long-Running Homogeneous VMs: Workloads are consistently deployed on long-running, homogeneously sized Virtual Machines (VMs), without variation or optimisation.
How to determine if this good enough
An organisation that relies on “Long-Running Homogeneous VMs” typically has static infrastructure: they stand up certain VM sizes—often chosen arbitrarily or based on outdated assumptions—and let them run continuously. For a UK public sector body, this may appear straightforward if:
Predictable, Low-Complexity Workloads
- Your compute usage doesn’t fluctuate much (e.g., a small number of internal line-of-business apps with stable user counts).
- You don’t foresee major surges or dips in demand.
- The overhead of changing compute sizes or rearchitecting to dynamic services might seem unnecessary.
Minimal Cost Pressures
- If your monthly spend is low enough to be tolerated within your departmental budget or you lack strong impetus from finance to optimise further.
- You might feel that it’s “not broken, so no need to fix it.”
Legacy Constraints
- Some local authority or government departments could be running older applications that are hard to containerise or re-platform. If you require certain OS versions or on-prem-like architectures, homogeneous VMs can seem “safe.”
Limited Technical Skills or Resources
- You may not have in-house expertise to manage containers, function-based services, or advanced orchestrators.
- If your main objective is stability and you have no immediate impetus to experiment, you might remain with static VM setups.
If you fall into these categories—low complexity, legacy constraints, stable usage, minimal cost concerns—then “Long-Running Homogeneous VMs” might indeed be “good enough.” However, many UK public sector cloud strategies now emphasize cost efficiency, scalability, and elasticity, especially under increased scrutiny of budgets and service reliability. Sticking to homogeneous, always-on VMs without optimisation can lead to wasteful spending, hamper agility, and prevent future readiness.
How to do better
Here are rapidly actionable improvements to help you move beyond purely static VMs:
Enable Basic Monitoring and Cost Insights
- Even if you keep long-running VMs, gather usage metrics and financial data:
- Check CPU, memory, and storage utilisation. If these metrics show consistent underuse (like 10% CPU usage around the clock), it’s a sign you can downsize or re-architect.
Leverage Built-in Right-sizing Tools
- Major cloud providers offer “right-sizing” recommendations:
- AWS Compute Optimiser to get suggestions for smaller or larger instance sizes.
- Azure Advisor for VM right-sizing to identify underutilised virtual machines.
- GCP Recommender for machine types to optimise resource utilisation.
- OCI Workload and Resource Optimisation for tailored resource recommendations.
- Make a plan to apply at least one or two right-sizing recommendations each quarter. This is a quick, low-risk path to cost savings and better resource use.
- Major cloud providers offer “right-sizing” recommendations:
Introduce Simple Scheduling
- If some VMs are only needed during business hours, schedule automatic shutdown at night or on weekends:
- A single action to stop dev/test or lightly used environments after hours can yield noticeable cost (and energy) savings.
Conduct a Feasibility Check for a Small Container Pilot
- Even if you retain most workloads on VMs, pick one small application or batch job and try containerising it:
- By piloting a single container-based workload, you can assess potential elasticity and determine whether container orchestration solutions meet your needs. This approach allows for quick experimentation with minimal risk.
Raise Awareness with Internal Stakeholders
- Share simple usage and cost graphs with your finance or leadership teams. Show them the difference between “always-on” vs. “scaled” or “scheduled” usage.
- This could drive more formal mandates or budget incentives to encourage partial re-architecture or adoption of short-lived compute in the future.
By monitoring usage, applying right-sizing, scheduling idle time, and introducing a small container pilot, you can meaningfully reduce waste. Over time, you’ll build momentum toward more flexible compute strategies while still respecting the constraints of your existing environment.
Primarily Long-Running VMs with Limited Experimentation: Most workloads are on long-running VMs, with some limited experimentation in containers or function-based services for non-critical tasks.
How to determine if this good enough
Organisations in this stage have recognised the benefits of more dynamic compute models—like containers or serverless—but apply them only in a small subset of cases. You might be “good enough” if:
Core Workloads Still Suited to Static VMs
- Perhaps your main applications are large, monolithic solutions that can’t easily shift to containers or functions.
- The complexity of re-platforming may outweigh the immediate gains.
Selective Use of Modern Compute
- You have tested container-based or function-based solutions for simpler tasks (e.g., cron jobs, internal scheduled data processing, or small web endpoints).
- The results are encouraging, but you haven’t had the internal capacity or business priority to expand further.
Comfortable Cost Baseline
- You’ve introduced auto-shutdown or partial right-sizing for your VMs, so your costs are not spiraling.
- Leadership sees no urgent impetus to push deeper into containers or serverless, perhaps because budgets remain stable or there’s no urgent performance/elasticity requirement.
Growing Awareness of Container or Serverless Advantages
- Some staff or teams are championing more frequent usage of advanced compute.
- The IT department sees potential, but organisational inertia, compliance considerations, or skill gaps limit widespread adoption.
If the majority of your mission-critical applications remain on VMs and you see stable performance within budget, this may be “enough” for now. However, if the cloud usage is expanding, or if your department is under pressure to modernise, you might quickly find you miss out on elasticity, cost efficiency, or resilience advantages that come from broader container or serverless adoption.
How to do better
Here are actionable next steps to accelerate your modernisation journey without overwhelming resources:
Expand Container/Serverless Pilots in a Structured Way
- Identify a short list of low-risk workloads that could benefit from ephemeral compute, such as batch processing or data transformation.
- Use native solutions to reduce complexity:
- AWS Fargate with ECS/EKS for container-based tasks without server management.
- Azure Container Apps or Azure Functions for event-driven workloads.
- Google Cloud Run for container-based microservices or Google Cloud Functions.
- Oracle Cloud Infrastructure (OCI) Container Instances or OCI Functions for short-lived tasks.
- Document real cost/performance outcomes to present a stronger case for further expansion.
Implement Granular VM Auto-Scaling
- Even with VMs, you can configure auto-scaling groups or scale sets to handle changing loads:
- This ensures you pay only for the capacity you need during peak vs. off-peak times.
Use Container Services for Non-Critical Production
- If you have a stable container proof-of-concept, consider migrating a small but genuine production workload. Examples:
- Internal APIs, internal data analytics pipelines, or front-end servers that can scale up/down.
- Focus on microservices that do not require extensive refactoring.
- This fosters real operational experience, bridging from “non-critical tasks” to “production readiness.”
- If you have a stable container proof-of-concept, consider migrating a small but genuine production workload. Examples:
Leverage Cloud Marketplace or Government Frameworks
- Explore container-based solutions or DevOps tooling that might be available under G-Cloud or Crown Commercial Service frameworks.
- Some providers offer managed container solutions pre-configured for compliance or security—this can reduce friction around governance.
Train or Upskill Teams
- Provide short courses or lunch-and-learns on container orchestration (Kubernetes, ECS, AKS, etc.) or serverless fundamentals.
- Many vendors have free or low-cost training:
Building confidence and skills helps teams adopt more advanced compute models.
Through these steps—structured expansions of containerised or serverless pilots, improved auto-scaling of VMs, and staff training—your organisation can gradually shift from “limited experimentation” to a more balanced compute ecosystem. The result is improved agility, potential cost savings, and readiness for more modern architectures.
Mixed Use with Some Advanced Compute Options: Some production workloads are run in containers or function-based compute services. Ad-hoc use of short-lived VMs is practiced, with efforts to right-size based on workload needs.
How to determine if this good enough
This stage indicates a notable transformation: your organisation uses multiple compute paradigms. You have container-based or serverless workloads in production, you sometimes spin up short-lived VMs for ephemeral tasks, and you’re actively right-sizing. It may be “good enough” if:
Functional, Multi-Modal Compute Strategy
- You’ve proven that containers or serverless can handle real production demands (e.g., public-facing services, departmental applications).
- VMs remain important for some workloads, but you adapt or re-size them more frequently.
Solid Operational Knowledge
- Your teams are comfortable deploying to a container platform (e.g., Kubernetes, ECS, Azure WebApps for containers, etc.) or using function-based services in daily workflows.
- Monitoring and alerting are configured for both ephemeral and long-running compute.
Balanced Cost and Complexity
- You have a handle on typical monthly spend, and finance sees a correlation between usage spikes and cost.
- You might not be fully optimising everything, but you rarely see large, unexplained bills.
Clear Upsides from Modern Compute
- You’ve recognised that certain microservices perform better or cost less on serverless or containers.
- Cultural buy-in is growing: multiple teams express interest in flexible compute models.
If these points match your environment, your “Mixed Use” approach might currently satisfy your user needs and budget constraints. However, you might still see opportunities to refine deployment methods, unify your management or monitoring, and push for greater elasticity. If you suspect further cost savings or performance gains are possible—or you want a more standardised approach across the organisation—further advancement is likely beneficial.
How to do better
Below are rapidly actionable ways to enhance your mixed compute model:
Adopt Unified Deployment Pipelines
- Strive for standard tooling that can deploy both VMs and container/serverless environments. For instance:
- AWS CodePipeline or AWS CodeBuild integrated with ECS, Lambda, EC2, etc.
- Azure Pipelines or GitHub Actions for VMs, AKS, Azure Functions.
- Google Cloud Build for GCE, GKE, Cloud Run deployments.
- OCI DevOps service for flexible deployments to OKE, Functions, or VMs.
- This reduces fragmentation and fosters consistent best practices (code review, automated testing, environment provisioning).
- Strive for standard tooling that can deploy both VMs and container/serverless environments. For instance:
Enhance Observability
- Implement a single monitoring stack that captures logs, metrics, and traces across VMs, containers, and functions:
- AWS CloudWatch combined with AWS X-Ray for distributed tracing in containers or Lambda.
- Azure Monitor along with Application Insights for containers and serverless telemetry.
- Google Cloud’s Operations Suite utilising Cloud Logging and Cloud Trace for multi-service environments.
- Oracle Cloud Infrastructure (OCI) Logging integrated with the Observability and Management Platform for cross-service insights.
- Unified observability ensures you can quickly identify inefficiencies or scaling issues.
- Implement a single monitoring stack that captures logs, metrics, and traces across VMs, containers, and functions:
Introduce a Tagging/Governance Policy
- Standardise tags or labels for cost center, environment, and application name. This practice aids in tracking spending, performance, and potential carbon footprint across various compute services.
- Utilise tools such as:
- Implementing a unified tagging strategy fosters accountability and helps identify usage patterns that may require optimisation.
Implement Automated or Dynamic Scaling
- For container-based workloads, set CPU and memory usage thresholds to enable auto-scaling of pods or tasks:
- For serverless architectures, establish concurrency or usage limits to prevent unexpected cost spikes.
Implementing these scaling strategies ensures that your applications can efficiently handle varying workloads while controlling costs.
Leverage Reserved or Discounted Pricing for Steady Components
- If certain VMs or container clusters must run continuously, investigate vendor discount models:
- Blend on-demand resources for elastic workloads with reservations for predictable baselines to optimise costs.
Implementing these strategies can lead to significant cost savings for workloads with consistent usage patterns.
By unifying your deployment practices, consolidating observability, enforcing tagging, and refining autoscaling or discount usage, you move from an ad-hoc mix of compute styles to a more cohesive, cost-effective cloud ecosystem. This sets the stage for robust, consistent governance and significant agility gains.
Regular Use of Short-Lived VMs and Containers: There is regular use of short-lived VMs and containers, along with some function-based compute services. This indicates a move towards more flexible and scalable compute options.
How to determine if this good enough
When your organisation regularly uses ephemeral or short-lived compute models, containers, and functions, you’ve likely embraced cloud-native thinking. This suggests:
Frequent Scaling and Automated Lifecycle
- You seldom keep large VMs running 24/7 unless absolutely necessary.
- Container-based architectures or ephemeral VMs scale up to meet demand, then terminate when idle.
High Automation in CI/CD
- Deployments to containers or serverless happen automatically via pipelines.
- Infrastructure provisioning is likely codified in IaC (Infrastructure as Code) tooling (Terraform, CloudFormation, Bicep, etc.).
Performance and Cost Efficiency
- You typically pay only for what you use, cutting down on waste.
- Application performance can match demand surges without manual intervention.
Multi-Service Observability
- Monitoring covers ephemeral workloads, with logs and metrics aggregated effectively.
If you have reached this point, your environment is more agile, cost-optimised, and aligned with modern DevOps. However, you may still have gaps in advanced scheduling, deeper security or compliance integration, or a formal approach to evaluating each new solution (e.g., deciding between containers, serverless, or a managed SaaS).
How to do better
Below are actionable expansions to push your ephemeral usage approach further:
Adopt a “Compute Decision Framework”
- Formalise how new workloads choose among FaaS (functions), CaaS (containers), or short-lived VMs:
- If event-driven with spiky traffic, prefer serverless.
- If the service requires consistent runtime dependencies but can scale, prefer containers.
- If specialised hardware or older OS is needed briefly, use short-lived VMs.
- This standardisation helps teams quickly pick the best fit.
- Formalise how new workloads choose among FaaS (functions), CaaS (containers), or short-lived VMs:
Enable Event-Driven Automation
- Use events to trigger ephemeral jobs:
- AWS EventBridge or CloudWatch Events to invoke Lambda or spin up ECS tasks.
- Azure Event Grid or Logic Apps triggering Functions or container jobs.
- GCP Pub/Sub or EventArc calls Cloud Run services or GCE ephemeral jobs.
- OCI Events Service integrated with Functions or autoscaling rules.
- This ensures resources only run when triggered, further minimising idle time.
- Use events to trigger ephemeral jobs:
Implement Container Security Best Practices
- As ephemeral container usage grows, so do potential security concerns:
- Use AWS ECR scanning or Amazon Inspector for container images.
- Use Azure Container Registry (ACR) image scanning with Microsoft Defender for Cloud.
- Use GCP Container Registry or Artifact Registry with scanning and Google Cloud Security Command Center.
- Use OCI Container Registry scanning and Security Zones for container compliance.
- Integrate scans into your CI/CD pipeline for immediate alerts and automation.
- As ephemeral container usage grows, so do potential security concerns:
Refine Infrastructure as Code (IaC) and Pipeline Patterns
- Standardise ephemeral environment creation using:
- AWS CloudFormation or AWS CDK, plus AWS CodePipeline.
- Azure Resource Manager templates or Bicep, plus Azure DevOps or GitHub Actions.
- GCP Deployment Manager or Terraform, with Cloud Build triggers.
- OCI Resource Manager for stack deployments, integrated with OCI DevOps pipeline.
- Encourage a shared library of environment definitions to accelerate new project spin-up.
- Standardise ephemeral environment creation using:
Extend Tagging and Cost Allocation
Since ephemeral resources come and go quickly, ensure they are labeled or tagged upon creation.
Set up budgets or cost alerts to identify if ephemeral usage unexpectedly spikes:
By formalising your decision framework, expanding event-driven architectures, ensuring container security, and strengthening IaC patterns, you solidify your short-lived compute model. This approach reduces overheads, fosters agility, and helps UK public sector teams remain compliant with cost and operational excellence targets.
‘Fit for Purpose’ Approach with Rigorous Right-sizing: Cloud services selection is driven by a strict ‘fit for purpose’ approach. This includes a rigorous continual right-sizing process and a solution evaluation hierarchy favoring SaaS > FaaS > Containers as a Service > Platform/Orchestrator as a Service > Infrastructure as a Service.
How to determine if this good enough
At this highest maturity level, you explicitly choose the most appropriate computing model—often starting from SaaS (Software as a Service) if it meets requirements, then serverless if custom code is needed, then containers, and so on down to raw VMs only when necessary. Indicators that this might be “good enough” include:
Every New Project Undergoes a Thorough Fit Assessment
- Your solution architecture process systematically asks: “Could an existing SaaS platform solve this? If not, can serverless do the job? If not, do we need container orchestration?” and so forth.
- This approach prevents defaulting to IaaS or large container clusters without strong justification.
Rigorous Continual Right-sizing
- Teams actively measure usage and adjust resource allocations monthly or even weekly.
- Underutilised resources are quickly scaled down or replaced by ephemeral compute. Over-stressed services are scaled up or moved to more robust solutions.
Sophisticated Observability, Security, and Compliance
- With multiple service layers, you maintain consistent monitoring, security scanning, and compliance checks across SaaS, FaaS, containers, and IaaS.
- You have well-documented runbooks and automated pipelines to handle each technology layer.
Cost Efficiency and Agility
- Budgets often reflect usage-based spending, and spikes are quickly noticed.
- Development cycles are faster because you adopt higher-level services first, focusing on business logic rather than infrastructure management.
If your organisation can demonstrate that each new or existing application sits in the best-suited compute model—balancing cost, compliance, and performance—this is typically considered the pinnacle of cloud compute maturity. However, continuous improvements in vendor offerings, emerging technologies, and changing departmental requirements mean there is always more to refine.
How to do better
Even at this advanced state, you can still hone practices. Below are suggestions:
Automate Decision Workflows
- Build an internal “Service Catalog” or “Decision Tree.” For instance:
- A web-based form that asks about the workload’s functional, regulatory, performance, and cost constraints, then suggests suitable solutions (SaaS, FaaS, containers, etc.).
- This can be integrated with pipeline automation so new projects must pass through the framework before provisioning resources.
- Build an internal “Service Catalog” or “Decision Tree.” For instance:
Deepen SaaS Exploration for Niche Needs
- Explore specialised SaaS options for areas like data analytics, content management, or identity services.
- Ensure your staff or solution architects regularly revisit the G-Cloud listings or other Crown Commercial Service frameworks to see if an updated SaaS solution can replace custom-coded or container-based systems.
Further Standardise DevOps Across All Layers
- If you run FaaS on multiple clouds or keep some workloads on private cloud, unify your deployment approach.
- Encourage a single pipeline style:
- AWS CodePipeline or GitHub Actions for everything from AWS Lambda to Amazon ECS, plus AWS CloudFormation for infrastructure as code.
- Azure DevOps for .NET-based function apps, container solutions like Azure Container Instances, or Azure Virtual Machines under one roof.
- Google Cloud Build triggers that handle Cloud Run, Google Compute Engine, or third-party SaaS integrations.
- Oracle Cloud Infrastructure (OCI) DevOps pipeline for a mixed environment using Oracle Kubernetes Engine (OKE), Oracle Functions, or third-party webhooks.
Maintain a Living Right-sizing Strategy
- Expand beyond memory/CPU metrics to measure cost per request, concurrency, or throughput.
- Tools like:
- AWS Compute Optimiser advanced metrics for EBS I/O, Lambda concurrency, etc.
- Azure Monitor Workbooks with custom performance/cost insights
- GCP Recommenders for scaling beyond just CPU/memory (like disk usage suggestions)
- OCI Observability with granular resource usage metrics for compute and storage optimisation
Focus on Energy Efficiency and Sustainability
- Refine your approach with a strong environmental lens:
- Pick regions or times that yield lower carbon intensity, if permitted by data residency rules.
- Enforce ephemeral usage policies to avoid running resources unnecessarily.
- Each vendor offers sustainability or carbon data to inform your “fit for purpose” decisions:
- Refine your approach with a strong environmental lens:
Champion Cross-Public-Sector Collaboration
- Share lessons or templates with other departments or agencies. This fosters consistent best practices across local councils, NHS trusts, or central government bodies.
By automating your decision workflows, continuously exploring SaaS, standardising DevOps pipelines, and incorporating advanced metrics (including sustainability), you maintain an iterative improvement path at the peak of compute maturity. This ensures you remain agile in responding to new user requirements and evolving government initiatives, all while controlling costs and optimising resource efficiency.
Keep doing what you’re doing, and consider writing up success stories, internal case studies, or blog posts. Submit pull requests to this guidance or relevant public sector best-practice repositories so others can learn from your achievements. By sharing real-world experiences, you help the entire UK public sector enhance its cloud compute maturity.
How does your organisation plan, measure, and optimise the environmental sustainability and carbon footprint of its cloud compute resources?
Basic Vendor Reliance: Sustainability isn’t actively measured internally; reliance is placed on cloud vendors who are contractually obligated to work towards carbon neutrality, likely through offsetting.
How to determine if this good enough
In this stage, your organisation trusts its cloud provider to meet green commitments through mechanisms like carbon offsetting or renewable energy purchases. You likely have little to no visibility of actual carbon metrics. For UK public sector bodies, you might find this acceptable if:
- Limited Scope and Minimal Usage
- Your cloud footprint is extremely small (e.g., a handful of testing environments).
- The cost and complexity of internal measurement may not seem justified at this scale.
- No Immediate Policy or Compliance Pressures
- You face no urgent departmental or legislative requirement to detail your carbon footprint.
- Senior leadership may not yet be asking for sustainability reports.
- Strong Confidence in Vendor Pledges
- Your contract or statements of work (SoW) reassure you that the provider is pursuing net zero or carbon neutrality.
- You have no immediate impetus to verify or go deeper into the supply chain or usage details.
If you are in this situation and operate with minimal complexity, “Basic Vendor Reliance” might be temporarily “good enough.” However, the UK public sector is increasingly required to evidence sustainability efforts, particularly under initiatives like the Greening Government Commitments. Larger or rapidly growing workloads will likely outgrow this approach. If you anticipate expansions, cost concerns, or scrutiny from oversight bodies, it is wise to move beyond vendor reliance.
How to do better
Below are rapidly actionable steps that provide greater visibility and ensure you move beyond mere vendor assurances:
Request Vendor Transparency
- Ask your provider for UK-region-specific energy usage information and carbon intensity data. For example:
- Even if the data is approximate, it helps you begin to monitor trends.
Enable Basic Billing and Usage Reports
- Activate native cost-and-usage tooling to gather baseline compute usage:
- AWS Cost Explorer with daily or hourly granularity.
- Azure Cost Management
- GCP Billing Export to BigQuery
- OCI Cost Analysis
- While these tools focus on monetary spend, you can correlate usage data with the vendor’s sustainability information.
- Activate native cost-and-usage tooling to gather baseline compute usage:
Incorporate Sustainability Clauses in Contracts
- When renewing or issuing new calls on frameworks like G-Cloud, add explicit language for carbon reporting.
- Request quarterly or annual updates on how your usage ties into the vendor’s net-zero or carbon offset strategies.
Incorporating sustainability clauses into your contracts is essential for ensuring that your cloud service providers align with your environmental goals. The Crown Commercial Service offers guidance on integrating such clauses into the G-Cloud framework. Additionally, the Chancery Lane Project provides model clauses for environmental performance, which can be adapted to your contracts.
By proactively including these clauses, you can hold vendors accountable for their sustainability commitments and ensure that your organisation’s operations contribute positively to environmental objectives.
Track Internal Workload Growth
- Even if you rely on vendor neutrality claims, set up a simple spreadsheet or a lightweight tracker for each of your main cloud workloads (service name, region, typical CPU usage, typical memory usage). If usage grows, you will notice potential new carbon hotspots.
Raise Internal Awareness
- Create a short briefing note for leadership or relevant teams (e.g., finance, procurement) highlighting:
- Your current reliance on vendor offsetting, and
- The need for baseline data collection.
This ensures any interest in deeper environmental reporting can gather support before usage grows further.
- Create a short briefing note for leadership or relevant teams (e.g., finance, procurement) highlighting:
Initial Awareness and Basic Policies: Some basic policies and goals for sustainability are set. Efforts are primarily focused on awareness and selecting vendors with better environmental records.
How to determine if this good enough
At this stage, you have moved beyond “vendor says they’re green.” You may have a written policy stating that you will prioritise environmentally responsible suppliers or aim to reduce your cloud emissions. For UK public sector organisations, “Initial Awareness” may be adequate if:
Formal Policy Exists, but Execution Is Minimal
- You have a documented pledge or departmental instruction to pick greener vendors or to reduce carbon, but it’s largely aspirational.
Some Basic Tracking or Guidance
- Procurement teams might refer to environmental credentials during tendering, especially if you’re using Crown Commercial Service frameworks.
- Staff are aware that sustainability is important, but lack practical steps.
Minimal External Oversight
- You might not yet be required to publish detailed carbon metrics in annual reports or meet stringent net zero timelines.
- The policy helps reduce reputational risk, but you have not turned it into tangible workflows.
This approach is a step up from total vendor reliance. However, it often lacks robust measurement or accountability. If your workload, budget, or public scrutiny around environmental impact is increasing—particularly in line with the Greening Government Commitments you will likely need more rigorous strategies soon.
How to do better
Here are quick wins to strengthen your approach and make it more actionable:
Use Vendor Sustainability Tools for Basic Estimation
- Enable the carbon or sustainability dashboards in your chosen cloud platform to get monthly or quarterly snapshots:
Create Simple Internal Guidelines
- Expand beyond policy statements:
- Resource Tagging: Mandate that every new resource is tagged with an owner, environment, and a sustainability tag (e.g., “non-prod, auto-shutdown” vs. “production, high-availability”).
- Preferred Regions: If feasible, prefer data centers that the vendor identifies as more carbon-friendly. For example, some AWS and Azure UK-based regions rely on greener energy sourcing than others.
- Expand beyond policy statements:
Schedule Simple Sustainability Checkpoints
- Alongside your standard procurement or architectural reviews, add a sustainability review item. E.g.:
- “Does the new service use the recommended low-carbon region?”
- “Is there a plan to power down dev/test resources after hours?”
- This ensures your new policy is not forgotten in day-to-day activities.
- Alongside your standard procurement or architectural reviews, add a sustainability review item. E.g.:
Offer Quick Training or Knowledge Sessions
- Host short lunch-and-learn events or internal micro-training on “Cloud Sustainability 101” for staff. Show them how they can use:
The point is to connect cost optimisation with sustainability—over-provisioned resources burn more carbon.
Publish Simple Reporting
- Create a once-a-quarter dashboard or presentation highlighting approximate cloud emissions. Even if the data is partial or not perfect, transparency drives accountability.
By rapidly applying these steps—using native vendor tools to measure usage, establishing minimal but meaningful guidelines, and scheduling brief training or check-ins—you elevate your policy from mere awareness to actual practice.
Active Measurement and Target Setting: The organisation actively measures its cloud compute carbon footprint and sets specific targets for reduction. This includes choosing cloud services based on their sustainability metrics.
How to determine if this good enough
Here, you have begun quantifying your cloud-based carbon output. You might set yearly or quarterly reduction goals (e.g., a 10% decrease in carbon from last year). You also factor environmental impacts into your choice of instance types, storage classes, or regions. Signs this might be “good enough” include:
Regular Carbon Footprint Data
- You have monthly or quarterly reports from vendor dashboards or a consolidated internal system (e.g., pulling data from cost/billing APIs plus vendor carbon intensity metrics).
Formal Targets and Milestones
- Leadership acknowledges these targets. They appear in your departmental objectives or technology strategy.
Procurement Reflects Sustainability
- RFQs or tenders explicitly weigh sustainability factors, awarding points to vendors or proposals that commit to lower carbon usage.
- You might require prospective suppliers to share energy efficiency data for their services.
Leadership or External Bodies Approve
- Senior managers or oversight bodies see your target-setting approach as credible.
- Your reports are used in annual reviews or compliance documentation.
While “Active Measurement and Target Setting” is a robust step forward, you may still discover that your usage continues to increase due to scaling demands or new digital services. Additionally, you might lack advanced optimisation practices like continuous resource right-sizing or dynamic load shifting.
How to do better
Focus on rapid, vendor-native steps to convert targets into tangible reductions:
Automate Right-sizing
- Many providers have native tools to recommend more efficient instance sizes:
- AWS Compute Optimiser to identify underutilised EC2, EBS, or Lambda resources
- Azure Advisor Right-sizing for VMs and databases
- GCP Recommender for VM rightsizing
- OCI Adaptive Intelligence for resource optimisation
By automatically resizing or shifting to lower-tier SKUs, you reduce both cost and emissions.
- Many providers have native tools to recommend more efficient instance sizes:
Implement Scheduled Autoscaling
- Introduce or refine your autoscaling policies so that workloads scale down outside peak times:
This directly lowers carbon usage by removing idle capacity.
Leverage Serverless or Container Services
- Where feasible, re-platform certain workloads to serverless or container-based architectures that scale to zero. Rapid wins can be found by:
Serverless can significantly cut wasted resources, which aligns with your reduction targets.
Adopt “Carbon Budgets” in Project Plans
- For every new app or service, define a carbon allowance. If estimates exceed the budget, require design changes. Incorporate vendor solutions that show region-level carbon data:
These tools provide insights into the carbon emissions associated with different regions, enabling more sustainable decision-making.
- Align with Departmental or National Sustainability Goals
- Update your internal reporting to reflect how your targets link to national net zero obligations or departmental commitments (e.g., the NHS net zero plan, local authority climate emergency pledges). This ensures your measurement and goals remain relevant to broader public sector accountability.
Implementing these steps swiftly helps ensure you don’t just measure but actually reduce your carbon footprint. Regular iteration—checking usage data, right-sizing, adjusting autoscaling—ensures continuous progress toward your stated targets.
Integrated Sustainability Practices: Sustainability is integrated into cloud resource planning and usage. This includes regular monitoring and reporting on sustainability metrics and making adjustments to improve environmental impact.
How to determine if this good enough
At this stage, sustainability isn’t a separate afterthought—it’s part of your default operational processes. Indications that you might be “good enough” for UK public sector standards include:
Frequent/Automated Monitoring
- Carbon metrics are tracked at least weekly, if not daily, using integrated dashboards.
- You have alerts for unexpected surges in usage or carbon-intense resources.
Cultural Adoption Across Teams
- DevOps, procurement, and governance leads all know how to incorporate sustainability criteria.
- Architects regularly consult carbon metrics during design sessions, akin to how they weigh cost or security.
Regular Public or Internal Reporting
- You might publish simplified carbon reports in your annual statements or internally for senior leadership.
- Stakeholders can see monthly/quarterly improvements, reflecting a stable, integrated practice.
Mapping to Strategic Objectives
- The departmental net zero or climate strategy references your integrated approach as a key success factor.
- You can demonstrate tangible synergy: e.g., your cost savings from scaling down dev environments are also cutting carbon.
Despite these achievements, additional gains can still be made, especially in advanced workload scheduling or region selection. If you want to stay ahead of new G-Cloud requirements, carbon scoring frameworks, or stricter net zero mandates, you may continue optimising your environment.
How to do better
Actionable steps to deepen your integrated approach:
Set Up Automated Governance Rules
- Enforce region-based or instance-based policies automatically:
- AWS Service Control Policies to block high-carbon region usage in non-essential cases
- Azure Policy for “Allowed Locations” or “Tagging Enforcement” with sustainability tags
- GCP Organisation Policy to limit usage to certain carbon-friendly regions
- OCI Security Zones or policies restricting resource deployment
- Enforce region-based or instance-based policies automatically:
Implementing these policies ensures that resources are deployed in regions with lower carbon footprints, aligning with your sustainability objectives.
Adopt Full Lifecycle Management
- Extend sustainability beyond compute:
- Automate data retention: Move older data to cooler or archive storage for lower energy usage:
- Review ephemeral development: Ensure test environments are automatically cleaned after a set period.
- Extend sustainability beyond compute:
Use Vendor-Specific Sustainability Advisors
- Some providers offer “sustainability pillars” or specialised frameworks:
Incorporate these suggestions directly into sprint backlogs or monthly improvement tasks.
Embed Sustainability in DevOps Pipelines
- Modify build/deployment pipelines to check resource usage or region selection:
- If a new environment is spun up in a high-carbon region or with large instance sizes, the pipeline can prompt a warning or require an override.
- Tools like GitHub Actions or Azure DevOps Pipelines can call vendor APIs to fetch sustainability metrics and fail a build if it’s non-compliant.
- Modify build/deployment pipelines to check resource usage or region selection:
Promote Cross-Functional “Green Teams”
- Form a small working group or “green champions” network across procurement, DevOps, governance, and finance, meeting monthly to share best practices and track new optimisation opportunities.
- This approach keeps your integrated practices dynamic, ensuring you respond quickly to new vendor features or updated government climate guidance.
By adding these automated controls, pipeline checks, and cross-functional alignment, you ensure that your integrated sustainability approach not only continues but evolves in real time. You become more agile in responding to shifting requirements and new tools, maintaining a leadership stance in UK public sector cloud sustainability.
Advanced Optimisation and Dynamic Management: Advanced strategies are in place, like automatic time and location shifting of workloads to minimise impact. Data retention and cloud product selection are deeply aligned with sustainability goals and carbon footprint metrics.
How to determine if this good enough
At the pinnacle of cloud sustainability maturity, your organisation leverages sophisticated methods such as:
Real-Time or Near-Real-Time Workload Scheduling
- When feasible and compliant with data sovereignty, you shift workloads to times/locations with lower carbon intensity.
- You may monitor the UK grid’s real-time carbon intensity and schedule large batch jobs during off-peak, greener times.
Full Lifecycle Carbon Costing
- Every service or data set has an associated “carbon cost,” influencing decisions from creation to archival/deletion.
- You constantly refine how your application code runs to reduce unnecessary CPU cycles, memory usage, or data transfers.
Continuous Improvement Culture
- Teams treat carbon optimisation as essential as cost or performance. Even minor improvements (e.g., 2% weekly CPU usage reduction) are celebrated.
Cross-Government Collaboration
- As a leader, you might share advanced scheduling or dynamic region selection techniques with other public sector bodies.
- You might co-publish guidance for G-Cloud or Crown Commercial Service frameworks on advanced sustainability requirements.
If you have truly dynamic optimisation but remain within the constraints of UK data protection or performance needs, you have likely achieved a highly advanced state. However, there’s almost always room to push boundaries, such as exploring new hardware (e.g., ARM-based servers) or adopting emergent best practices in green software engineering.
How to do better
Even at this advanced level, below are further actions to refine your dynamic management:
Build or Leverage Carbon-Aware Autoscaling
- Many providers offer advanced scaling rules that consider multiple signals. Integrate carbon signals:
- AWS EventBridge + Lambda triggers that check region carbon intensity before scaling up large clusters
- Azure Monitor + Azure Functions to re-schedule HPC tasks when the grid is greener
- GCP Cloud Scheduler + Dataflow for time-shifted batch jobs based on carbon metrics
- OCI Notifications + Functions to enact advanced scheduling policies
- Many providers offer advanced scaling rules that consider multiple signals. Integrate carbon signals:
Collaborate with BEIS or Relevant Government Bodies
- The Department for Business, Energy & Industrial Strategy (BEIS) or other departments may track grid-level carbon. If you can integrate their public data (e.g., real-time carbon intensity in the UK), you can refine your scheduling.
- Seek synergy with national digital transformation or sustainability pilot programmes that might offer new tools or funding for experimentation.
AI or ML-Driven Forecasting
- Incorporate predictive analytics that forecast your usage spikes and align them with projected carbon intensity (peak/off-peak). Tools like:
Then automatically shift or throttle workloads accordingly.
Innovate with Low-Power Hardware
- Evaluate next-gen or specialised hardware solutions with lower energy profiles:
Typically, these instance families consume less energy for similar workloads, further reducing carbon footprints.
Automated Data Classification and Tiering
- For advanced data management, use AI to classify data in real-time and automatically place it in the most sustainable storage tier:
This ensures minimal energy overhead for data retention.
Set an Example through Openness
- If compliance allows, publish near real-time dashboards illustrating your advanced scheduling successes or hardware usage.
- Share code or Infrastructure-as-Code templates with other public sector teams to accelerate mutual learning.
By implementing these advanced tactics, you sharpen your dynamic optimisation approach, continuously pushing the envelope of what’s possible in sustainable cloud operations—while respecting legal constraints around data sovereignty and any performance requirements unique to public services.
Keep doing what you’re doing, and consider documenting or blogging about your experiences. Submit pull requests to this guidance so other UK public sector organisations can accelerate their own sustainability journeys. By sharing real-world results and vendor-specific approaches, you help shape a greener future for public services across the entire nation.
What approaches does your organisation use to plan, measure, and optimise cloud spending?
Restricted Billing Visibility: Billing details are only accessible to management and finance teams, with limited transparency across the organisation.
How to determine if this good enough
Restricted Billing Visibility typically implies that your cloud cost data—such as monthly bills, usage breakdowns, or detailed cost analytics—remains siloed within a small subset of individuals or departments, usually finance or executive leadership. This might initially appear acceptable if you believe cost decisions do not directly involve engineering teams, product owners, or other stakeholders. It can also seem adequate when your organisation is small, or budgets are centrally controlled. However, carefully assessing whether this arrangement still meets your current and emerging needs requires a closer look at multiple dimensions: stakeholder awareness, accountability for financial outcomes, cross-functional collaboration, and organisational growth.
Stakeholder Awareness and Alignment
- When only a narrow group (e.g., finance managers) knows the full cost details, other stakeholders may make decisions in isolation, unaware of the larger financial implications. This can lead to inflated resource provisioning, missed savings opportunities, or unexpected billing surprises.
- Minimal cost visibility might still be sufficient if your organisation’s usage is predictable, your budget is stable, and your infrastructure is relatively small. In such scenarios, cost control may not be a pressing concern. Nevertheless, even in stable environments, ignoring cost transparency could result in incremental increases that go unnoticed until they become significant.
Accountability for Financial Outcomes
- Finance teams that are solely responsible for paying the bill and analyzing cost trends might not have enough granular knowledge of the engineering decisions driving those costs. If your developers or DevOps teams are not looped in, they cannot easily optimise code, infrastructure, or architecture to reduce waste.
- This arrangement can be considered “good enough” if your service-level agreements demand minimal overhead from engineers, or if your leadership structure is comfortable with top-down cost directives. However, the question remains: are you confident that your engineering teams have no role to play in optimising usage patterns? If the answer is that engineers do not need to see cost data to be efficient, you might remain in this stage without immediate issues. But typically, as soon as your environment grows in complexity, the limitation becomes evident.
Cross-Functional Collaboration
- Siloed billing data hinders cross-functional input and collaboration. Product managers, engineering leads, and operational teams may not easily communicate about the cost trade-offs associated with new features, expansions, or refactoring.
- This might be “good enough” if your operating model is highly centralised and decisions about capacity, performance, or service expansion are made primarily through a few financial gatekeepers. Yet, even in such a centralised model, growth or changing business goals frequently demand more nimble, collaborative approaches.
Scalability Concerns and Future Growth
- When usage scales or new product lines are introduced, a lack of broader cost awareness can quickly escalate monthly bills. If your environment remains small or has limited growth, you might not face immediate cost explosions.
- However, any potential business pivot—such as adopting new cloud services, launching in additional regions, or implementing a continuous delivery model—might cause your costs to spike in ways that a small finance-only group cannot effectively preempt.
Risk Assessment
- A direct risk in “Restricted Billing Visibility” is the possibility of accumulating unnecessary spend because the people who can make technical changes (engineers, developers, or DevOps) do not have the insight to detect cost anomalies or scale down resources.
- If your usage remains modest and you have a proven track record of stable spending without sudden spikes, maybe it is still acceptable to keep cost data limited to finance. Nonetheless, you run the risk of missing optimisation pathways if your environment changes or if external factors (e.g., vendor price adjustments) affect your spending patterns.
In summary, this approach may be “good enough” for organisations with very limited complexity or strictly centralised purchasing structures where cost fluctuations remain low and stable. It can also suffice if you have unwavering trust that top-down oversight alone will detect anomalies. But if you see any potential for cost spikes, new feature adoption, or a desire to empower engineering with cost data, it might be time to consider a more transparent model.
How do I do better?
How do I do better?
If you want to improve beyond “Restricted Billing Visibility,” the next step typically involves democratising cost data. This transition does not mean giving everyone unrestricted access to sensitive financial accounts or payment details. Instead, it centers on making relevant usage and cost breakdowns accessible to those who influence spending decisions, such as product owners, development teams, and DevOps staff, in a manner that is both secure and comprehensible.
Below are tangible ways to create a more open and proactive cost culture:
Role-Based Access to Billing Dashboards
- Most major cloud providers offer robust billing dashboards that can be securely shared with different levels of detail. For example, you can configure specialised read-only roles that allow developers to see usage patterns and daily cost breakdown without granting them access to critical financial settings.
- Look into official documentation and solutions from your preferred cloud provider:
- AWS: AWS Cost Explorer
- Azure: Azure Cost Management
- GCP: Cloud Billing Reports
- OCI: Oracle Cloud Cost Analysis
- By carefully configuring role-based access, you enable various teams to monitor cost drivers without exposing sensitive billing details such as invoicing or payment methods.
Regular Cost Review Meetings
- Schedule short, recurring meetings (monthly or bi-weekly) where finance, engineering, operations, and leadership briefly review cost trends. This fosters collaboration, encourages data-driven decisions, and allows everyone to ask questions or highlight anomalies.
- Ensure these sessions focus on actionable items. For instance, if a certain service’s spend has doubled, discuss whether that trend reflects legitimate growth or a misconfiguration that can be quickly fixed.
Automated Cost Alerts for Key Stakeholders
- Integrating cost alerts into your organisational communication channels can be a game changer. Instead of passively waiting for monthly bills, set up cost thresholds, daily or weekly cost notifications, or usage anomalies that get shared in Slack, Microsoft Teams, or email distribution lists.
- This approach ensures that the right people see cost increases in near real-time. If a developer spins up a large instance for testing and forgets to turn it off, you can catch that quickly.
- Each major provider offers alerting and budgeting features:
Cost Dashboards Embedded into Engineering Workflows
- Rather than expecting developers to remember to check a separate financial console, embed cost insights into the tools they already use. For example, if your organisation relies on a continuous integration/continuous deployment (CI/CD) pipeline, you can integrate scripts or APIs that retrieve daily cost data and present them in your pipeline dashboards or as part of a daily Slack summary.
- Some organisations incorporate cost metrics into code review processes, ensuring that changes with potential cost implications (like selecting a new instance type or enabling a new managed service) are considered from both a technical and financial perspective.
Empowering DevOps with Cost Governance
- If you have a DevOps or platform engineering team, involve them in evaluating cost optimisation best practices. By giving them partial visibility into real-time spend data, they can quickly adjust scaling policies, identify over-provisioned resources, or investigate usage anomalies before a bill skyrockets.
- You might create a “Cost Champion” role in each engineering squad—someone who monitors usage, implements resource tagging strategies, and ensures that the rest of the team remains mindful of cloud spend.
Use of FinOps Principles
- The emerging discipline of FinOps (short for “Financial Operations”) focuses on bringing together finance, engineering, and business stakeholders to drive financial accountability. Adopting a FinOps mindset means cost visibility becomes a shared responsibility, with iterative improvement at its core.
- Consider referencing frameworks like the FinOps Foundation’s Principles to learn about building a culture of cost ownership, unit economics, and cross-team collaboration.
Security and Compliance Considerations
- Improving visibility does not mean exposing sensitive corporate finance data or violating compliance rules. Many organisations adopt an approach where top-level financial details (like credit card info or total monthly invoice) remain restricted, but usage-based metrics, daily cost reports, and resource-level data are made available.
- Work with your governance or risk management teams to ensure that any expanded visibility aligns with data protection regulations and internal security policies.
By following these strategies, you shift from a guarded approach—where only finance or management see the details—to a more inclusive cost culture. The biggest benefit is that your engineering teams gain the insight they need to optimise continuously. Rather than discovering at the end of the month that a test environment was running at full throttle, teams can detect and fix potential overspending early. Over time, this fosters a sense of shared cost responsibility, encourages more efficient design decisions, and drives proactive cost management practices across the organisation.
Proactive Spend Commitment by Finance: The finance team uses billing information to make informed decisions about pre-committed cloud spending where it’s deemed beneficial.
How to determine if this good enough
In many organisations, cloud finance teams or procurement specialists negotiate contracts with cloud providers for discounted rates based on committed spend, often referred to as “Reserved Instances,” “Savings Plans,” “Committed Use Discounts,” or other vendor-specific programs. This approach can result in significant cost savings if done correctly. Understanding when this level of engagement is “good enough” often depends on the maturity of your cost forecasting, the stability of your workloads, and the alignment of these financial decisions with actual technical usage patterns.
Consistent, Predictable Workloads
- If your application usage is relatively stable or predictably growing, pre-committing spend for a year or multiple years may deliver significant savings. In these situations, finance-led deals—where finance is looking at historical bills and usage curves—can cover the majority of your resource requirements without risking over-commitment.
- This might be “good enough” if your organisation already has a stable architecture and does not anticipate major changes that could invalidate these predictions.
Finance Has Access to Accurate Usage Data
- The success of pre-commit or reserved instances depends on the accuracy of usage forecasts. If finance can access granular, up-to-date usage data from your environment—and if that data is correct—then they can make sound financial decisions regarding commitment levels.
- This approach is likely “good enough” if your technical teams and finance teams have established a reliable process for collecting and interpreting usage metrics, and if finance is skilled at comparing on-demand rates with potential discounts.
Minimal Input from Technical Teams
- Sometimes, organisations rely heavily on finance to decide how many reserved instances or committed usage plans to purchase. If your technical environment is not highly dynamic or if there is low risk that engineering changes will undermine those pre-commit decisions, centralising decision-making in finance might be sufficient.
- That said, if your environment is subject to bursts of innovation, quick scaling, or sudden shifts in resource types, you risk paying for commitments that do not match your actual usage. If you do not see a mismatch emerging, you might feel comfortable with the status quo.
No Urgent Need for Real-Time Adjustments
- One reason an exclusively finance-led approach might still be “good enough” is that you have not observed frequent or large mismatches between your committed usage and your actual consumption. The cost benefits appear consistent, and you have not encountered major inefficiencies (like leftover capacity from partially utilised commitments).
- If your workloads are largely static or have a slow growth pattern, you may not require real-time collaboration with engineering. Under those circumstances, a purely finance-driven approach can still yield moderate or even significant savings.
Stable Vendor Relationships
- Some organisations prefer to maintain strong partnerships with a single cloud vendor and do not plan on multi-cloud or vendor migration strategies. If you anticipate staying with that vendor for the long haul, pre-commits become less risky.
- If you have confidence that your vendor’s future services or pricing changes will not drastically shift your usage patterns, you might view finance’s current approach as meeting your needs.
However, this arrangement can quickly become insufficient if your organisation experiences frequent changes in technology stacks, product lines, or scaling demands. It may also be suboptimal if you do not track how the commitments are being used—or if finance does not engage with the technical side to refine usage estimates.
How do I do better?
How do I do better?
To enhance a “Proactive Spend Commitment by Finance” model, organisations often evolve toward deeper collaboration between finance, engineering, and product teams. This ensures that negotiated contracts and reserved purchasing decisions accurately reflect real workloads, growth patterns, and future expansions. Below are methods to improve:
Integrated Forecasting and Capacity Planning
- Instead of having finance make decisions based purely on past billing, establish a forecasting model that includes planned product launches, major infrastructure changes, or architectural transformations.
- Encourage technical teams to share roadmaps (e.g., upcoming container migrations, new microservices, or expansions into different regions) so finance can assess whether existing reservation strategies are aligned with future reality.
- By merging product timelines with historical usage data, finance can negotiate better deals and tailor them closely to the actual environment.
Dynamic Monitoring of Reservation Coverage
- Use vendor-specific tools or third-party solutions to track your reservation utilisation in near-real-time. For instance:
- Continuously reviewing coverage lets you adjust reservations if your provider or plan permits it. Some vendors allow you to modify instance families, shift reservations to different regions, or exchange them for alternative instance sizes, subject to specific constraints.
Cross-Functional Reservation Committees
- Create a cross-functional group that meets quarterly or monthly to decide on reservation purchases or modifications. In this group, finance presents cost data, while engineering clarifies usage patterns and product owners forecast upcoming demand changes.
- This ensures that any new commits or expansions account for near-future workloads rather than only historical data. If you adopt agile practices, incorporate these reservation reviews as part of your sprint cycle or program increment planning.
Leverage Spot or Preemptible Instances for Variable Workloads
- An advanced tactic is to blend long-term reservations for predictable workloads with short-term, highly cost-effective instance types—such as AWS Spot Instances, Azure Spot VMs, GCP Preemptible VMs, or OCI Preemptible Instances—for workloads that can tolerate interruptions.
- Finance-led pre-commits for baseline needs plus engineering-led strategies for ephemeral or experimental tasks can minimise your total cloud spend. This synergy requires communication between finance and engineering so that the latter group can identify which workloads can safely run on spot capacity.
Refining Commitment Levels and Terms
- If your cloud vendor offers multiple commitment term lengths (e.g., 1-year vs. 3-year reservations, partial upfront vs. full upfront) and different coverage tiers, refine your strategy to match usage stability. For example, if 60% of your workload is unwavering, consider 3-year commits; if another 20% fluctuates, opt for 1-year or on-demand.
- Over time, as your usage data becomes more accurate and your architecture stabilises, you can shift more workloads into longer-term commitments for greater discounts. Conversely, if your environment is in flux, keep your commitments lighter to avoid overpaying.
Unit Economics and Cost Allocation
- Enhance your commitment strategy by tying it to unit economics—i.e., cost per customer, cost per product feature, or cost per transaction. Once you can express your cloud bills in terms of product-level or service-level metrics, you gain more clarity on which areas most justify pre-commits.
- If you identify a specific product line that reliably has N monthly active users, and you have stable usage patterns there, you can base reservations on that product’s forecast. Then, the cost savings from reservations become more attributable to specific products, making budgeting and cost accountability smoother.
Ongoing Financial-Technical Collaboration
- Beyond initial negotiations, keep the lines of communication open. Cloud resource usage is dynamic, particularly with continuous integration and deployment practices. Having monthly or quarterly check-ins between finance and engineering ensures you track coverage, refine cost models, and respond quickly to usage spikes or dips.
- Consider forming a “FinOps” group if your cloud usage is substantial. This multi-disciplinary team can use data from daily or weekly cost dashboards to fine-tune reservations, detect anomalies, and champion cost-optimisation strategies across the business.
By progressively weaving in these improvements, you move from a purely finance-led contract negotiation model to one where decisions about reserved spending or commitments are strongly informed by real-time engineering data and future product roadmaps. This more holistic approach leads to higher reservation utilisation, fewer wasted commitments, and better alignment of your cloud spending with actual business goals. The result is typically a more predictable cost structure, improved cost efficiency, and reduced risk of paying for capacity you do not need.
Cost-Effective Resource Management: Cloud environments and applications are configured for cost-efficiency, such as automatically shutting down or scaling down non-production environments during off-hours.
How to determine if this good enough
Cost-Effective Resource Management typically reflects an environment where you have implemented proactive measures to eliminate waste in your cloud infrastructure. Common tactics include turning off development or testing environments at night, using auto-scaling to handle variable load, and continuously auditing for idle resources. The question becomes whether these tactics alone suffice for your organisational goals or if further improvements are necessary. To evaluate, consider the following:
Monitoring Actual Savings
- If you have systematically scheduled non-production workloads to shut down or scale down during off-peak hours, you should be able to measure the direct savings on your monthly bill. Compare your pre-implementation spending to current levels, factoring in seasonal usage patterns. If your cost has dropped significantly, you might conclude that the approach is providing tangible value.
- However, cost optimisation rarely stops at shutting down test environments. If you still observe large spikes in bills outside of work hours or suspect that production environments remain over-provisioned, you may not be fully leveraging the potential.
Resource Right-sizing
- Simply scheduling off-hours shutdowns is beneficial, but right-sizing resources can yield equally impactful or even greater results. For instance, if your production environment runs on instance types or sizes that are consistently underutilised, there is an opportunity to downsize.
- If you have not yet performed or do not regularly revisit right-sizing exercises—analyzing CPU and memory usage, optimising storage tiers, or removing unused IP addresses or load balancers—your “Cost-Effective Resource Management” might only be addressing part of the savings puzzle.
Lifecycle Management of Environments
- Shutting down entire environments for nights or weekends helps reduce cost, but it is only truly effective if you also manage ephemeral environments responsibly. Are you spinning up short-lived staging or test clusters for continuous integration, but forgetting to tear them down after usage?
- If you have robust processes or automation that handle the entire lifecycle—creation, usage, shutdown, deletion—for these environments, then your current approach could be “good enough.” If not, orphaned or abandoned environments might still be draining budgets.
Auto-Scaling Maturity
- Auto-scaling is a cornerstone of cost-effective resource management. If you have implemented it for your production and major dev/test environments, that may appear “good enough” initially. But is your scaling policy well-optimised? Are you aggressively scaling down during low traffic, or do you keep large buffer capacities?
- Evaluate logs to check if you have frequent periods of near-zero usage but remain scaled up. If auto-scaling triggers are not finely tuned, you could be missing out on further cost reductions.
Cost vs. Performance Trade-Offs
- Some teams accept a degree of cost inefficiency to ensure maximum performance. If your organisation is comfortable paying for extra capacity to handle traffic bursts, the existing environment might be adequate. But if you have not explicitly weighed the financial cost of that performance margin, you could be inadvertently overspending.
- “Good enough” might be an environment where you have at least set baseline checks to prevent runaway spending. Yet, if you want to refine performance-cost trade-offs further, additional tuning or service re-architecture could unlock more savings.
Empowerment of Teams
- Another dimension is whether only a small ops or DevOps group is responsible for shutting down resources or if the entire engineering team is cost-aware. If the latter is not the case, you may have manual processes that lead to inconsistent application of off-hour shutdowns. A more mature approach would see each team taking responsibility for their resource usage, aided by automation.
- If your processes remain centralised and manual, your approach might hit diminishing returns as you grow. Achieving real momentum often requires embedding cost awareness into the entire software development lifecycle.
When you reflect on these factors, “Cost-Effective Resource Management” is likely “good enough” if you have strong evidence of direct savings, a minimal presence of unused resources, and a consistent approach to shutting down or scaling your environments. If you still detect untracked resources, underused large instances, or an absence of automated processes, there are plenty of next steps to enhance your strategy.
How do I do better?
How do I do better?
If you wish to refine your cost-efficiency, consider adding more sophisticated processes, automation, and cultural practices. Here are ways to evolve:
Implement More Granular Auto-Scaling Policies
- Move beyond simple CPU-based or time-based triggers. Incorporate multiple metrics (memory usage, queue depth, request latency) so you scale up and down more precisely. This ensures that environments adjust capacity as soon as traffic drops, boosting your savings.
- Evaluate advanced solutions from your cloud provider:
Use Infrastructure as Code for Environment Management
- Instead of ad hoc creation and shutdown scripts, adopt Infrastructure as Code (IaC) tools (e.g., Terraform, AWS CloudFormation, Azure Bicep, Google Deployment Manager, or OCI Resource Manager) to version-control environment configurations. Combine IaC with schedule-based or event-based triggers.
- This approach ensures that ephemeral environments are consistently built and torn down, leaving minimal risk of leftover resources. You can also implement automated tagging to track cost by environment, team, or project.
Re-Architect for Serverless or Containerised Workloads
- If your application can tolerate stateless, event-driven, or container-based architectures, consider adopting serverless computing (e.g., AWS Lambda, Azure Functions, GCP Cloud Functions, OCI Functions) or container orchestrators (e.g., Kubernetes, Docker Swarm).
- These models often scale to zero when no requests are active, ensuring you only pay for actual usage. While not all workloads are suitable, re-architecting certain components can yield significant cost improvements.
Optimise Storage and Networking
- Cost-effective management extends beyond compute. Look for opportunities to move infrequently accessed data to cheaper storage tiers, such as object storage archive classes or lower-performance block storage. Configure lifecycle policies to purge logs or snapshots after a specified retention.
- Monitor data transfer costs between regions, availability zones, or external endpoints. If your architecture unnecessarily routes traffic through costlier paths, consider direct inter-region or peering solutions that reduce egress charges.
Scheduled Resource Hibernation and Wake-Up Processes
- Extend beyond typical off-hour shutdowns by creating fully automated schedules for every environment that does not require 24/7 availability. For instance, set a policy to shut down dev/test resources at 7 p.m. local time, and spin them back up at 8 a.m. the next day.
- Tools or scripts can detect usage anomalies (e.g., someone working late) and override the schedule or send a prompt to confirm if the environment should remain active. This approach ensures maximum cost avoidance, especially for large dev clusters or specialised GPU instances.
Incorporate Cost Considerations into Code Reviews and Architecture Decisions
- Foster a culture in which cost is a first-class design principle. During code reviews, developers might highlight the cost implications of using a high-tier database service, retrieving data across regions, or enabling a premium feature.
- Architecture design documents should include estimated cost breakdowns, referencing official pricing details for the services involved. Over time, teams become more adept at spotting potential overspending.
Automated Auditing and Cleanup
- Implement scripts or tools that run daily or weekly to detect unattached volumes, unused IP addresses, idle load balancers, or dormant container images. Provide automated cleanup or at least raise alerts for manual review.
- Many cloud providers have built-in recommendations engines:
- AWS: AWS Trusted Advisor
- Azure: Azure Advisor
- GCP: Recommender Hub
- OCI: Oracle Cloud Advisor
Track and Celebrate Savings
- Publicise cost optimisation wins. If an engineering team shaved 20% off monthly bills by fine-tuning auto-scaling, celebrate that accomplishment in internal communications. Show the before/after metrics to encourage others to follow suit.
- This positive reinforcement helps maintain momentum and fosters a sense of shared ownership.
By layering these enhancements, you move beyond basic scheduling or minimal auto-scaling. Instead, you cultivate a deeply ingrained practice of continuous optimisation. You harness automation to enforce best practices, integrate cost awareness into everyday decisions, and systematically re-architect services for maximum efficiency. Over time, the result is a lean cloud environment that can expand when needed but otherwise runs with minimal waste.
Cost-Aware Development Practices: Developers and engineers have daily visibility into cloud costs and are encouraged to consider the financial impact of their choices in the development phase.
How to determine if this good enough
Introducing “Cost-Aware Development Practices” means your engineering teams are no longer coding in a vacuum. Instead, they have direct or near-direct access to cost data and incorporate budget considerations throughout their software lifecycle. However, measuring if this approach is “good enough” requires assessing how deeply cost awareness is embedded in day-to-day technical activities, as well as the outcomes you achieve.
Extent of Developer Engagement
- If your developers see cloud cost dashboards daily but rarely take any action based on them, the visibility may not be translating into tangible benefits. Are they actively tweaking infrastructure choices, refactoring code to reduce memory usage, or questioning the necessity of certain services? If not, your “awareness” might be superficial.
- Conversely, if you see frequent pull requests that address cost inefficiencies, your development team is likely using their visibility effectively.
Integration in the Software Development Lifecycle
- Merely giving developers read access to a billing console is insufficient. If your approach is truly effective, cost discussions happen early in design or sprint planning, not just at the end of the month. The best sign is that cost considerations appear in architecture diagrams, code reviews, and platform selection processes.
- If cost is still an afterthought—addressed only when a finance or leadership team raises an alarm—then the practice is not yet “good enough.”
Tooling and Automated Feedback
- Effective cost awareness often involves integrated tooling. For instance, developers might see near real-time cost metrics in their Git repositories or continuous integration workflows. They might receive a Slack notification if a new branch triggers resources that exceed certain thresholds.
- If your environment lacks this real-time or near-real-time feedback loop, and developers only see cost data after big monthly bills, the awareness might be lagging behind actual usage.
Demonstrable Cost Reductions
- A simple yardstick is whether your engineering teams can point to quantifiable cost reductions linked to design decisions or code changes. For example, a team might say, “We replaced a full-time VM with a serverless function and saved $2,000 monthly.”
- If such examples are sparse or non-existent, you might suspect that cost awareness is not yet translating into meaningful changes.
Cultural Embrace
- A “good enough” approach sees cost awareness as a normal part of engineering culture, not an annoying extra. Team leads, product owners, and developers frequently mention cost in retrospectives or stand-ups.
- If referencing cloud spend or budgets still feels taboo or is seen as “finance’s job,” you have further to go.
Alignment with Company Goals
- Finally, consider how your cost-aware practices align with broader business goals—whether that be margin improvement, enabling more rapid scaling, or launching new features within certain budgets. If your engineering changes consistently support these objectives, your approach might be sufficiently mature.
- If leadership is still blindsided by unexpected cost overruns or if big swings in usage go unaddressed, it is likely that your cost-aware culture is not fully effective.
How do I do better?
How do I do better?
If you want to upgrade your cost-aware development environment, you can deepen the integration of financial insight into everyday engineering. Below are practical methods:
Enhance Toolchain Integrations
- Provide cost data directly in the platforms developers use daily:
- Pull Request Annotations: When a developer opens a pull request in GitHub or GitLab that adds new cloud resources (e.g., creating a new database or enabling advanced analytics), an automated comment could estimate the monthly or annual cost impact.
- IDE Plugins: Investigate or develop plugins that estimate cost implications of certain library or service calls. While advanced, such solutions can drastically reduce guesswork.
- CI/CD Pipeline Steps: Incorporate cost checks as a gating mechanism in your CI/CD process. If a change is projected to exceed certain cost thresholds, it triggers a review or a labeled warning.
- Provide cost data directly in the platforms developers use daily:
Reward and Recognition Systems
- Implement a system that publicly acknowledges or rewards teams that achieve significant cost savings or code optimisations that reduce the cloud bill. This can be a monthly “cost champion” award or a highlight in the company-wide newsletter.
- Recognising teams for cost-smart decisions helps embed a culture where financial prudence is celebrated alongside feature delivery and reliability.
Cost Education Workshops
- Host internal workshops or lunch-and-learns where experts (whether from finance, DevOps, or a specialised FinOps team) explain how cloud billing works, interpret usage graphs, or share best practices for cost-efficient coding.
- Make these sessions as practical and example-driven as possible: walk developers through real code and show the difference in cost from alternative approaches.
Tagging and Chargeback/Showback Mechanisms
- Encourage consistent resource tagging so that each application component or service is clearly attributed to a specific team, project, or feature. This tagging data feeds into cost reports that let you see which code bases or squads are driving usage.
- You can then implement a “showback” model (where each team sees the monthly cost of their resources) or a “chargeback” model (where those costs directly affect team budgets). Such financial accountability often motivates more thoughtful engineering decisions.
Guidelines and Architecture Blueprints
- Produce internal reference guides that show recommended patterns for cost optimisation. For example, specify which database types or instance families are preferred for certain workloads. Provide example Terraform modules or CloudFormation templates that are pre-configured for cost-efficiency.
- Encourage developers to consult these guidelines when designing new systems. Over time, the default approach becomes inherently cost-aware.
Frequent Feedback Loops
- Implement daily or weekly cost digests that are automatically posted in relevant Slack channels or email lists. These digests highlight the top 5 cost changes from the previous period, giving engineering teams rapid insight into where spend is shifting.
- Additionally, create a channel or forum where developers can ask cost-related questions in real time, ensuring they do not have to guess how a new feature might affect the budget.
Collaborative Budgeting and Forecasting
- For upcoming features or architectural revamps, involve engineers in forecasting the cost impact. By inviting them into the financial planning process, you ensure they understand the budgets they are expected to work within.
- Conversely, finance or product managers can learn from engineers about the real operational complexities, leading to more accurate forecasting and fewer unrealistic cost targets.
Adopt a FinOps Mindset
- Expand on the FinOps principles beyond finance alone. Encourage all engineering teams to take part in continuous cost optimisation cycles—inform, optimise, and operate. In these cycles, you measure usage, identify opportunities, experiment with changes, and track results.
- Over time, cost efficiency becomes an ongoing practice rather than a one-time initiative.
By adopting these approaches, you elevate cost awareness from a passive, occasional concern to a dynamic, integrated element of day-to-day development. This deeper integration helps your teams design, code, and deploy with financial considerations in mind—often leading to innovative solutions that deliver both performance and cost savings.
Comprehensive Cost Management and Optimisation: Multi-tier spend alerts are configured to notify various levels of the business for immediate action. Developers and engineers regularly review and prioritise changes to improve cost-effectiveness significantly.
Comprehensive Cost Management and Optimisation represents a mature stage in your organisation’s journey toward efficient cloud spending. At this point, cost transparency and accountability span multiple layers—from frontline developers to senior leadership. You have automated alerting structures in place to catch anomalies quickly, you track cost optimisation initiatives with the same rigor as feature delivery, and you’ve embedded cost considerations into operational runbooks. Below are key characteristics and actionable guidance to maintain or further refine this approach:
Robust and Granular Alerting Mechanisms
- In a comprehensive model, you’ve configured multi-tier alerts that scale with the significance of cost changes. For instance, a modest daily threshold might notify a DevOps Slack channel, while a larger monthly threshold might email department heads, and an even bigger spike might trigger urgent notifications to executives.
- Ensure these alerts are not just numeric triggers (e.g., “spend exceeded $X”), but also usage anomaly detections. For example, if a region’s usage doubles overnight or a new instance type’s cost surges unexpectedly, the right people receive immediate alerts.
- Each major cloud provider offers flexible budgeting and cost anomaly detection:
Cross-Functional Cost Review Cadences
- You have regular reviews—often monthly or quarterly—where finance, engineering, operations, and leadership analyze trends, track the outcomes of previous optimisation initiatives, and identify new areas of improvement.
- During these sessions, metrics might include cost per application, cost per feature, cost as a percentage of revenue, or carbon usage if sustainability is also a focus. This fosters a culture where cost is not an isolated item but a dimension of overall business performance.
Prioritisation of Optimisation Backlog
- In a comprehensive system, cost optimisation tasks are often part of your backlog or project management tool (e.g., Jira, Trello, or Azure Boards). Engineers and product owners treat these tasks with the same seriousness as performance issues or feature requests.
- The backlog might include refactoring older services to more modern compute platforms, consolidating underutilised databases, or migrating certain workloads to cheaper regions. By regularly ranking and scheduling these items, you show a commitment to continuous improvement.
End-to-End Visibility into Cost Drivers
- True comprehensiveness means your teams can pinpoint exactly which microservice, environment, or user activity drives each cost spike. This is usually achieved through detailed tagging strategies, advanced cost allocation methods, or third-party tools that break down usage in near-real-time.
- If a monthly cost review reveals that data transfer is trending upward, you can directly tie it to a new feature that streams large files, or a microservice that inadvertently calls an external API from an expensive region. You then take targeted action to reduce those costs.
Forecasting and Capacity Planning
- Beyond reviewing past or current costs, you systematically forecast future spend based on product roadmaps and usage growth. This might involve building predictive models or leveraging built-in vendor forecasting tools.
- Finance and engineering collaborate to refine these forecasts, adjusting resource reservations or scaling strategies accordingly. For example, if you anticipate doubling your user base in Q3, you proactively adjust your reservations or budgets to avoid surprises.
Policy-Driven Automation and Governance
- Comprehensive cost management often includes policy enforcement. For instance, you may have automated guardrails that prevent developers from spinning up large GPU instances without approval, or compliance checks that ensure data is placed in cost-efficient storage tiers when not actively in use.
- Some organisations implement custom or vendor-based governance solutions that block resource creation if it violates cost or security policies. This ensures cost best practices become part of the standard operating procedure.
Continuous Feedback Loop and Learning
- The hallmark of a truly comprehensive approach is the cyclical process of learning from cost data, making improvements, measuring outcomes, and then repeating. Over time, each iteration yields a more agile and cost-efficient environment.
- Leadership invests in advanced analytics, A/B testing for cost optimisation strategies (e.g., testing a new auto-scaling policy in one region), and might even pilot different cloud vendors or hybrid deployments to see if further cost or performance benefits can be achieved.
Scaling Best Practices Across the Organisation
- In a large enterprise, you may have multiple business units or product lines. A comprehensive approach ensures that cost management practices do not remain siloed. You create a central repository of best practices, standard operating procedures, or reference architectures to spread cost efficiency across all teams.
- This might manifest as an internal “community of practice” or “center of excellence” for FinOps, where teams share success stories, compare metrics, and continually push the envelope of optimisation.
Aligning Cost Optimisation with Business Value
- Ultimately, cost optimisation should serve the broader strategic goals of the business—whether to improve profit margins, free up budget for innovation, or support sustainability commitments. In the most advanced organisations, decisions around cloud architecture tie directly to metrics like cost per transaction, cost per user, or cost per new feature.
- Senior executives see not just raw cost figures but also how those costs translate to business outcomes (e.g., revenue, user retention, or speed of feature rollout). This alignment cements cost optimisation as a catalyst for better products, not just an expense reduction exercise.
Evolving Toward Continuous Refinement
- Even with a high level of maturity, the cloud landscape shifts rapidly. Providers introduce new instance types, new discount structures, or new services that might yield better cost-performance ratios. An ongoing commitment to learning and experimentation keeps you ahead of the curve.
- Your monthly or quarterly cost reviews might always include a segment to evaluate newly released vendor features or pricing models. By piloting or migrating to these offerings, you ensure you do not stagnate in a changing market.
In short, “Comprehensive Cost Management and Optimisation” implies that every layer—people, process, and technology—is geared toward continuous financial efficiency. Alerts ensure no cost anomaly goes unnoticed, cross-functional reviews nurture a culture of accountability, and an active backlog of cost-saving initiatives keeps engineering engaged. Over time, this integrated approach can yield substantial and sustained reductions in cloud spend while maintaining or even enhancing the quality and scalability of your services.
Keep doing what you’re doing, and consider writing up your experiences in blog posts or internal knowledge bases, then submitting pull requests to this guidance so that others can learn from your successes. By sharing, you extend the culture of cost optimisation not only across your organisation but potentially across the broader industry.
What strategies guide your decisions on geographical distribution and operational management of cloud workloads and data storage?
Intra-Region Distribution: Workloads and data are spread across multiple availability zones within a single region to enhance availability and resilience.
How to determine if this good enough
- Moderate Tolerance for Region-Level Outages
You may handle an AZ-level failure but might be vulnerable if the entire region goes offline. - Improved Availability Over Single AZ
Achieving at least multi-AZ deployment typically satisfies many public sector continuity requirements, referencing NCSC’s resilience guidelines. - Cost vs. Redundancy
Additional AZ usage may raise costs (like cross-AZ data transfer fees), but many find the availability trade-off beneficial.
If you still have concerns about entire regional outages or advanced compliance demands for multi-region or cross-geography distribution, consider a multi-region approach. NIST SP 800-53 CP (Contingency Planning) controls often encourage broader geographical resiliency if your RPO/RTO goals are strict.
How to do better
Below are rapidly actionable ways to refine an intra-region approach:
Enable Automatic Multi-AZ Deployments
- e.g., AWS Auto Scaling groups across multiple AZs, Azure VM Scale Sets in multiple zones, GCP Managed Instance Groups (MIGs) or multi-zonal regional clusters, OCI multi-AD distribution for compute/storage.
- Minimises manual overhead for distributing workloads.
Replicate Data Synchronously
- For databases, consider regionally resilient services:
- Ensures quick failover if one Availability Zone (AZ) fails.
Set AZ-Aware Networking
- Deploy separate subnets or load balancers for each Availability Zone (AZ) so traffic automatically reroutes upon an AZ failure:
- Ensures high availability and fault tolerance by distributing traffic across multiple AZs.
Regularly Test AZ Failover
- Induce a partial Availability Zone (AZ) outage or rely on “game days” to ensure applications properly degrade or failover:
- Referencing NCSC guidance on vulnerability management.
- Ensures systems can handle unexpected disruptions effectively.
- Induce a partial Availability Zone (AZ) outage or rely on “game days” to ensure applications properly degrade or failover:
Monitor Cross-AZ Costs
- Some vendors charge for data transfer between AZs, so monitor usage with AWS Cost Explorer, Azure Cost Management, GCP Billing, OCI Cost Analysis.
By automatically spreading workloads, replicating data in multiple AZs, ensuring AZ-aware networking, regularly testing failover, and monitoring cross-AZ costs, you solidify your organisation’s resilience within a single region while controlling costs.
Selective Multi-Region Utilisation: An additional, legally compliant non-UK region is used for specific purposes, such as non-production workloads, certain data types, or as part of disaster recovery planning.
How to determine if this good enough
- Basic Multi-Region DR or Lower-Cost Testing
You might offload dev/test to another region or keep backups in a different region for DR compliance. - Minimal Cross-Region Dependencies
If you only replicate data or run certain non-critical workloads in the second region, partial coverage might suffice. - Meets Certain Compliance Needs
Some public sector entities require data in at least two distinct legal jurisdictions—this setup may address that in limited scope.
If entire production workloads are mission-critical for national services or must handle region-level outages seamlessly, you might consider a more robust multi-region active-active approach. NIST SP 800-34 DR guidelines often advise multi-region for critical continuity.
How to do better
Below are rapidly actionable improvements:
Automate Cross-Region Backups
- e.g., AWS S3 Cross-Region Replication, Azure Backup to another region, GCP Snapshot replication, OCI cross-region object replication.
- Minimises manual tasks and ensures consistent DR coverage.
Schedule Non-Production in Cheaper Regions
- If cost is a driver, shut down dev/test in off-peak times or run them in a region with lower rates:
- Referencing your chosen vendor’s regional pricing page.
- If cost is a driver, shut down dev/test in off-peak times or run them in a region with lower rates:
Establish a Basic DR Plan
- For the second region, define how you’d bring up minimal services if the primary region fails:
Regularly Test Failover
- Do partial or full DR exercises at least annually, ensuring data in the second region can spin up quickly.
- Referencing NIST SP 800-34 DR test recommendations or NCSC operational resilience playbooks.
Plan for Data Residency
- If using non-UK regions, confirm any legal constraints on data location, referencing GOV.UK data residency rules or relevant departmental guidelines.
By automating cross-region backups, offloading dev/test workloads where cost is lower, defining a minimal DR plan, regularly testing failover, and ensuring data residency compliance, you expand from a single-region approach to a modest but effective multi-region strategy.
Capability and Sustainability-Driven Selection: Regions are chosen based solely on their technical capabilities, cost-effectiveness, and environmental sustainability credentials, without any specific technical constraints.
How to determine if this good enough
- Advanced Region Flexibility
You pick the region that offers the best HPC, GPU, or AI services, or one with the lowest carbon footprint or cost. - Sustainability & Cost Prioritised
If your organisation strongly values green energy sourcing or cheaper nighttime rates, you shift workloads accordingly. - No Hard Legal Data Residency Constraints
You can store data outside the UK or EEA as permitted, and no critical constraints block you from picking any global region.
If you want to adapt in real time based on cost or carbon intensity or maintain advanced multi-region failover automatically, consider a dynamic approach. NCSC’s guidance on green hosting or multi-region usage and NIST frameworks for dynamic cloud management can guide advanced scheduling.
How to do better
Below are rapidly actionable enhancements:
Sustainability-Driven Tools
- e.g., AWS Customer Carbon Footprint Tool, Azure Carbon Optimisation, GCP Carbon Footprint, OCI Carbon Footprint.
- Evaluate region choices for best environmental impact.
Implement Real-Time Cost & Perf Monitoring
- Track usage and cost by region daily or hourly.
- Referencing AWS Cost Explorer, Azure Cost Management, GCP Billing Alerts, OCI Cost Analysis.
Enable Multi-Region Data Sync
- If you shift workloads for HPC or AI tasks, ensure data is pre-replicated to the chosen region:
Address Latency & End-User Performance
- For services with user-facing components, consider CDN edges, multi-region front-end load balancing, or local read replicas to ensure acceptable performance.
Document Region Swapping Procedures
- If you occasionally relocate entire workloads for cost or sustainability, define runbooks or scripts to manage DB replication, DNS updates, and environment spin-up.
By using sustainability calculators to choose greener regions, implementing real-time cost/performance checks, ensuring multi-region data readiness, managing user latency via CDNs or local replicas, and documenting region-swapping, you fully leverage each provider’s global footprint for cost and environmental benefits.
Dynamic and Cost-Sustainable Distribution: Workloads are dynamically allocated across various regions and availability zones, with scheduling optimised for cost-efficiency and sustainability, adapting in real-time to changing conditions.
How to determine if this good enough
Your organisation pursues a true multi-region, multi-AZ dynamic approach. Automated processes shift workloads based on real-time cost (spot prices) or carbon intensity, while preserving performance and compliance. This may be “good enough” if:
Highly Automated Infrastructure
- You rely on complex orchestration or container platforms that can scale or move workloads near-instantly.
Advanced Observability
- A robust system of metrics, logging, and anomaly detection ensures seamless adaptation to cost or sustainability triggers.
Continuous Risk & Compliance Checks
- Even though workloads shift globally, you remain compliant with relevant data sovereignty or classification rules, referencing NCSC data handling or departmental policies.
Nevertheless, you can refine HPC or AI edge cases, adopt chaos testing for dynamic distribution, or integrate advanced zero trust for each region shift. NIST SP 800-207 zero-trust architecture principles can help ensure each region transition remains secure.
How to do better
Below are rapidly actionable methods to refine dynamic, cost-sustainable distribution:
Automate Workload Placement
- Tools like [AWS Spot Instance with EC2 Fleet, Azure Spot VMs with scale sets, GCP Preemptible VMs, OCI Preemptible Instances] or container orchestrators that factor region costs:
- referencing vendor cost management APIs or third-party cost analytics.
- Tools like [AWS Spot Instance with EC2 Fleet, Azure Spot VMs with scale sets, GCP Preemptible VMs, OCI Preemptible Instances] or container orchestrators that factor region costs:
Use Real-Time Carbon & Pricing Signals
- e.g., AWS Instance Metadata + carbon data, Azure carbon footprint metrics, GCP Carbon Footprint reports, OCI sustainability stats.
- Shift workloads to the region with the best real-time carbon intensity or lowest spot price.
Add Continual Governance
- Ensure no region usage violates data residency constraints or compliance:
- referencing NCSC multi-region compliance advice or departmental data classification guidelines.
- Ensure no region usage violates data residency constraints or compliance:
Embrace Chaos Engineering
- Regularly test failover or region-shifting events to ensure dynamic distribution can recover from partial region outages or surges:
- Referencing NCSC guidance on chaos engineering or vendor solutions:
- These tools help simulate real-world disruptions, allowing you to observe system behavior and enhance resilience.
- Regularly test failover or region-shifting events to ensure dynamic distribution can recover from partial region outages or surges:
Integrate Advanced DevSecOps
- For each region shift, the pipeline or orchestrator re-checks security posture and cost thresholds in real time.
By automating workload placement with spot or preemptible instances, factoring real-time carbon and cost signals, applying continuous data residency checks, stress-testing region shifts with chaos engineering, and embedding advanced DevSecOps validations, you maintain a dynamic, cost-sustainable distribution model that meets the highest operational and environmental standards for UK public sector services.
Keep doing what you’re doing, and consider blogging about or opening pull requests to share how you handle multi-region distribution and operational management for cloud workloads.
