TL;DR
Most AWS bills shrink 20–40% by turning off idle resources, rightsizing instances, using Savings Plans for steady workloads, moving old data to cheaper storage tiers and setting budgets with alerts. Make cost a monthly review, not a yearly surprise.
Where does AWS spend usually go?
Compute, databases, storage and data transfer make up most bills. Start with Cost Explorer grouped by service and tag.
Which steps save the most?
- Delete idle load balancers, volumes and snapshots.
- Rightsize over-provisioned instances.
- Schedule non-production environments to stop at night.
- Buy Savings Plans for steady workloads.
- Use S3 lifecycle rules for old data.
- Cache with CloudFront to reduce transfer costs.
- Set budgets and anomaly alerts.
Key takeaways
- Idle resources are the fastest savings.
- Commit only for steady, predictable workloads.
- Review cost monthly with tags per project.
