S3 Batch operations

Having a good tagging strategy is part of recommended AWS account hygiene. Just like other initiatives, many of these strategies evolve over time. There may come a time when you or your organization feels the need to change some of the mandatory tags on the objects in your current set of S3 buckets.

This is where the power of AWS S3 Batch operations can come into play. It can perform batch operations on files and buckets with ease.

S3 Batch operations allow you to do more than just modify tags. The following operations can be performed with S3 Batch operations:
