Root Cause
What's happening

Cloud instances are provisioned with significantly more CPU and memory than workloads require.

Why it happens

Teams default to large instance types as a safety margin, and sizing is rarely revisited after initial deployment.

Explanation

Overprovisioning is the most common cloud cost waste. Teams select instance types based on peak-load assumptions or copy configurations from other services without profiling actual resource utilization. Instances running at 10-20% CPU utilization represent 80% wasted spend on compute.

Fix Plan
How to fix it
  1. 1.Analyze CPU and memory utilization metrics over the past 30 days to establish actual requirements
  2. 2.Downsize instances to the smallest type that sustains P95 utilization with comfortable headroom
  3. 3.Use auto-scaling groups to dynamically adjust capacity based on real-time demand
  4. 4.Consider burstable instance types (e.g., T3, T4g) for workloads with variable utilization patterns
  5. 5.Use cloud provider recommendation tools like AWS Compute Optimizer or GCP machine type recommendations

Right-size compute

Match instance types to actual utilisation to cut waste.

# AWS — get utilization recommendations
aws compute-optimizer get-ec2-instance-recommendations

# Kubernetes — check resource requests vs actual
kubectl top pods --containers

Always test changes in a safe environment before applying to production.

Prevention
How to prevent it
  • Require utilization data review before provisioning new instances
  • Schedule quarterly right-sizing reviews as part of FinOps practices
  • Implement auto-scaling by default for all non-static workloads

Frequently Asked Questions

How do I know if my instances are overprovisioned?

Check average and peak CPU/memory utilization. If average utilization is consistently below 30%, the instance is likely overprovisioned and can be downsized.

Will right-sizing cause performance issues?

Not if done with data. Size based on P95 utilization plus a safety margin. Use auto-scaling to handle unexpected peaks.
