How do you reduce AWS cloud costs?

A structured cost-reduction audit focuses on several areas:

1. Terminate Unused Resources: Delete detached EBS volumes, unused elastic IPs, and active NAT Gateways on empty VPCs.
2. Rightsizing: Analyze EC2/RDS metrics using CloudWatch and downsize underutilized instances.
3. Pricing Models: Commit to Spot instances for stateless workloads and Savings Plans for baseline compute.
4. Storage Tiers: Implement S3 lifecycle policies to transition old objects to Glacier.
