Rightsizing an underutilized VM fleet safely
WHAT IT TESTS: data-driven cost optimization. OUTLINE: gather multi-week percentile metrics across CPU, memory, network and disk; pick smaller or right-family types; roll out gradually with monitoring. RED FLAG: resizing on average CPU alone.
WHAT IT TESTS: whether you can rightsize from real telemetry rather than a single average. ANSWER OUTLINE: collect at least two to four weeks of percentile metrics across CPU, memory, network, and disk IOPS to capture peaks and seasonality; identify the binding constraint since memory or IO may matter more than CPU; choose a smaller or better-fit instance family; roll out canary-first with rollback and alerting.
