Claims a 10-30-50 rule for nonstop AWS savings: easy 10% wins by enabling S3 Intelligent‑Tiering (first two tiers) and switching gp2→gp3 (≈20% cheaper) and adding VPC endpoints to avoid data‑transfer charges; 30% wins by migrating self‑managed services to AWS managed services (Aurora, OpenSearch, SQS, SES) and aggressive Aurora bin‑packing (over 2,000 schemas on one cluster using db.r5.24xl, planning Graviton r6g for ~40% perf/$); 50% wins by rebuilding core apps on serverless APIs (DynamoDB, Cognito, AppSync, Amplify). Automation uses CloudFix and AWS Change Manager to implement fixes without admin credentials.
