QuestionQ27

Monitoring, Logging, Analysis, Remediation, and Performance Optimization

A company has scientists who upload large data objects to an Amazon S3 bucket using multipart uploads. These multipart uploads frequently fail because of poor end-client connectivity.

The company wants to optimize the storage costs associated with the data. A CloudOps engineer must implement a solution that displays metrics for incomplete uploads and automatically deletes any incomplete uploads after 7 days.

Which solution meets these requirements?

Explanation

Amazon S3 Storage Lens exposes the Incomplete Multipart Upload Bytes metric to report storage consumed by incomplete multipart uploads. An S3 Lifecycle rule using AbortIncompleteMultipartUpload can abort incomplete uploads after 7 days, deleting their uploaded parts and eliminating the associated storage cost.
