A company with hundreds of S3 buckets spread across many AWS accounts wants a single dashboard showing organization-wide metrics on storage usage, activity, and cost-optimisation opportunities, without having to query each bucket individually. Which S3 feature provides this?
- S3 Storage Lens
- S3 Object Lock
- S3 Requester Pays
- S3 Same-Region Replication
Why A? And why not the others?
Correct answer: A. S3 Storage Lens
S3 Storage Lens is built exactly for this purpose: it aggregates usage and activity metrics across an entire organization, including multiple accounts, Regions, and buckets, into interactive dashboards, so nobody has to query each bucket individually to understand storage trends or find cost-optimisation opportunities. Object Lock only prevents objects from being deleted or overwritten for a set period or indefinitely, for WORM compliance, and reports nothing about usage. Requester Pays only shifts who is billed for requests and transfer on a bucket and provides no analytics. Same-Region Replication copies objects to another bucket in the same Region for redundancy or compliance reasons; it is a data-movement feature, not a visibility or reporting feature.
