Reduce AWS Costs: 10 Tips to Cut Your Bill by Up to 40%

The "Cloud Tax"

AWS is like electricity: if you leave everything on in an empty house, you pay. Same for idle instances and unoptimized storage.

1. Find idle resources

Use AWS Trusted Advisor. If an EC2 instance has under 5% CPU for a week, it's a candidate to downsize or shut down.

2. S3 lifecycle policies

Don't keep all logs in Standard forever. Move old data to Glacier or delete automatically after 30 days.

3. Reserved Instances and Savings Plans

If you know you'll have a server for a year, don't pay on-demand. Commitment can save up to 70%.

4. Right-size to reality

Developers like to pick "t3.large" because it's comfortable. Most of the time t3.medium or even t3.small is enough.

5. Clean up orphaned EBS volumes

When you delete an EC2 instance, the disk (EBS) often remains. You keep paying for it.

6. Monitor and optimize bandwidth

Analyze Data Transfer Out costs. Use CloudWatch to alert on unusual spikes; consider CloudFront or Direct Connect for high egress.

7. Use Auto Scaling

Don't keep fixed instances if demand varies. Configure Auto Scaling groups to scale up or down with traffic or usage.

8. Remove old snapshots

Forgotten snapshots for deleted volumes are common. Use scripts or AWS CLI to list and remove snapshots past retention.

9. Review permissions and roles

Legacy projects often have unused accounts and roles. Clean up IAM (users, roles, policies) to reduce attack surface and avoid cost from unused services.

10. Optimize databases and RDS

Downsize underused RDS instances, remove test/temporary databases, enable automatic storage for Aurora or automatic backup cleanup.
