A marketing team stores data in Amazon S3 and uses versioning on some buckets. Multiple jobs write data to these buckets. To optimize storage costs, the company wants visibility into incomplete multipart uploads and obsolete object versions in the buckets. Which solution provides that information with the least operational effort?

Amazon S3 Storage Lens provides a dashboard that aggregates usage and activity metrics across all S3 buckets, including metrics for incomplete multipart uploads and noncurrent object versions. This offers a centralized view with minimal operational effort, as it's a built-in S3 feature. Running AWS CLI commands would require scripting and manual execution, increasing operational overhead. Amazon S3 Inventory reports can provide detailed object lists, but configuring and analyzing them specifically for these metrics is more involved than using Storage Lens's pre-computed metrics. AWS usage billing reports focus on cost and consumption, not specific object lifecycle states like incomplete multipart uploads or obsolete versions.
