Multi-region replication is a feature that enables you to deploy and use a single AWS Managed Microsoft AD directory across multiple AWS Regions. This makes it easier and more cost-effective for you to deploy and manage your Microsoft Windows and Linux workloads globally. With the automated multi-region replication capability you get higher resiliency, while your applications use a local directory for optimal performance. This feature is available in AWS Managed Microsoft AD (Enterprise Edition) only. You can use the feature for new and existing directories.
