Question

A company stores petabytes of data across hundreds of S3 buckets in multiple accounts within an AWS Organization. The finance team wants a single dashboard to identify buckets with large amounts of infrequently accessed data, incomplete multipart uploads consuming storage, and non-current version buildup so they can prioritize lifecycle policy changes across the organization. Which AWS capability best meets this requirement with the least effort?

Accepted Answer

Enable S3 Storage Lens with the advanced tier at the organization level to get aggregated usage and activity metrics and cost-optimization recommendations.

Answer

Enable S3 Server Access Logging on every bucket and query the logs with Amazon Athena to build a custom dashboard.

Answer

Use AWS Cost Explorer with daily granularity filtered by the S3 service to find high-cost buckets.

Answer

Turn on S3 Storage Class Analysis on each bucket individually and export the results to a spreadsheet.
