Compute Rightsizing Guide

Convert underutilization data into instance rightsizing actions.

Oversized compute is one of the fastest-growing waste sources in mature environments where workloads change over time.

Scan policy settings used for rightsizing thresholds and lookback tuning.
Use this playbook with scan results, owner validation, and export evidence.

Detection Signals

  • Sustained CPU and memory far below provisioned capacity.
  • High-cost instance families with low business-critical load.
  • Repeated recommendations in scan history across cycles.

Execution Steps

  1. Collect 7/14/30-day utilization baseline for each workload.
  2. Define candidate target size and rollback plan.
  3. Apply change during a low-risk maintenance window.
  4. Verify performance and update policy thresholds.
