How to Read Your AWS Bill Without Going Crazy
AWS billing files are notoriously cryptic. Target the most common sources of hidden waste instead of parsing every line item.
1. Idle VPC NAT Gateways
NAT Gateways charge a flat hourly rate plus data processing. Idle gateways across staging and production AZs waste hundreds of dollars monthly.
2. Orphaned and Overprovisioned EBS Storage
Unattached volumes and premium IOPS on test environments quietly accumulate charges. Snapshot, delete orphans, and rightsize developer disks.
3. Oversized RDS Databases Running 24/7
Pause non-production databases nights and weekends, or use serverless scaling so idle capacity does not burn budget.
Cost Allocation Strategy
Require tags for Project, Environment, and Owner so Cost Explorer can show clear accountability.
