Cost reviews usually start with instance sizes and reserved capacity. Those are worth doing, and they are finite. The recurring cost is set by data movement, storage tiering and how workloads scale.

- Egress and cross-zone traffic created by service placement
- Log and backup retention set once and never revisited
- Always-on environments that only get used during business hours
- Storage that never moves to a colder tier
