In this recipe, we will learn to implement cross-region replication with S3 buckets. If cross-region replication is enabled for a bucket, the data in a bucket is asynchronously copied to a bucket in another region. Cross-region replication provides better durability for data and aids disaster recovery. Replicating data may be also done for compliance and better latency.
