Notes on Cloud Cost Optimization

Small, boring changes that cut our monthly cloud bill by a third.

Most cloud cost savings are not glamorous: right-sizing instances, cleaning up orphaned volumes, and turning off staging environments overnight.

We set up automated reports flagging anything running above 80% idle for a week, which caught far more waste than any one-time audit did.

The third of our bill we cut came almost entirely from these boring, repeatable checks — not from a single clever architecture change.
