- Rightsize first. Anything averaging under 20% CPU for a month drops a size. No exceptions, no meetings.
- Graviton where it fits. Most stateless services move with a rebuild and run ~20% cheaper.
- Lifecycle your storage. S3 Intelligent-Tiering plus 90-day transitions clear the forgotten-bucket tax.
- Kill the zombies. Unattached EBS, idle load balancers, old snapshots — tag owners, wait two weeks, delete.
Takeaway: rightsizing, Graviton, and storage lifecycles clear 25–35% with zero architecture risk.
