Amazon DynamoDB now supports cross-region replication,a original feature that automatically replicates DynamoDB tables across AWS regions. You can employ cross-region replication to build globally distributed applications with lower-latency data access, better traffic management, and easier catastrophe recovery,and easier data migration. There is no additional charge for using the cross-region replication application. You only pay for Amazon DynamoDB resources for the replica tables, reading from Streams, or the SQS queue,and the EC2 instance that runs the cross-region application. You can get started today by reading How to Set Up Cross-Region Replication in the Amazon DynamoDB Developer Guide.,
