Cost OptimizationFinOpsRight-sizingReserved Instances 5 min read
Right-sizing, reserved capacity, spot instances, tagging and governance.
Three Pillars¶
- Visibility — tagging, cost allocation
- Optimization — RI, Savings Plans, spot
- Governance — budgets, alerts, policies
Quick Wins¶
- Shut down dev/staging outside working hours — ~65% savings
- Delete unused EBS, snapshots, EIPs
- S3 Lifecycle policies
- RI/Savings Plans — 30-72% savings
- Spot — up to 90% savings
- Graviton/ARM — 20% cheaper
Right-sizing¶
40% of instances use less than 20% CPU. AWS Cost Explorer rightsizing recommendations help identify them.
Summary¶
Cost optimization = continuous process. Tagging → right-sizing → commitment discounts.
