Improving your Amazon S3 security with cost-effective practices
summary
Recommends concrete S3 steps: flip large, cold datasets into intelligent tiering to capture the 50% savings one genomics customer achieved (saved ~$3M) while keeping millisecond reads; use S3 Inventory + S3 Batch to apply and extend locks; enable versioning and cap versions to stop “denial by wallet” attacks; test object lock in governance mode with short retention (one week → month) before moving to compliance; avoid single‑zone, watch lifecycle rules (creation vs access) and never apply a seven‑year compliance lock to the wrong bucket.
