Multi-Region replication - Amazon Directory Service
Benefits
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Multi-Region replication

Multi-Region replication can be used to automatically replicate your Amazon Managed Microsoft AD directory data across multiple Amazon Web Services Regions. This replication can improve performance for users and applications in disperse geographic locations. Amazon Managed Microsoft AD uses native Active Directory replication to replicate your directory’s data securely to the new Region.

Multi-Region replication is only supported for the Enterprise Edition of Amazon Managed Microsoft AD.

You can use automated multi-Region replication in most Regions where Amazon Managed Microsoft AD is available.

Benefits

With multi-Region replication in Amazon Managed Microsoft AD, Active Directory-aware applications use the directory locally for high performance and the multi-Region feature for resiliency. You can use multi-Region replication with Active Directory-aware applications like SharePoint and SQL Server Always On as well as Amazon services like Amazon RDS for SQL Server and FSx for Windows File Server. The following are additional benefits of multi-Region replication.

  • It lets you deploy a single Amazon Managed Microsoft AD instance globally, quickly, and eliminates the heavy lifting of self-managing a global Active Directory infrastructure.

  • It makes it easier and more cost-effective for you to deploy and manage Windows and Linux workloads in multiple Amazon Regions. Automated multi-Region replication enables optimal performance in your global Active Directory-aware applications. All applications deployed in Windows or Linux instances use Amazon Managed Microsoft AD locally in the Region, which enables responses to user requests from the closest Region possible.

  • It provides multi-Region resiliency. Deployed in the highly available Amazon managed infrastructure, Amazon Managed Microsoft AD handles automated software updates, monitoring, recovery, and the security of the underlying Active Directory infrastructure across all Regions. This allows you to focus on building your applications.
