This video demonstrates how to configure Amazon S3 Cross Region Replication, a feature that allows replicating objects from a source S3 bucket to a destination bucket in another AWS region. The presenter walks through the step-by-step process of setting up replication rules in the AWS Management Console, including enabling bucket versioning, selecting source and destination buckets, and configuring IAM roles. The tutorial covers use cases for cross-region replication such as compliance, latency reduction, and operational efficiency. It also shows how to test the replication by uploading a file to the source bucket and verifying its presence in the destination bucket. The video highlights that cross-region replication only applies to new objects, and existing objects require batch operations for replication.
