AWS Managed Microsoft AD adds Multi-Region replication for Opt-In regions

AWS Directory Service for Microsoft Active Directory, also known as AWS Managed Microsoft AD, now supports Multi-Region replication in AWS Opt-In regions. This expands the existing Multi-Region replication capability to additional AWS regions, eliminating the need to create and manually synchronize independent directories in each region and allowing domain-joined workloads in those regions to connect to AWS Managed Microsoft AD. With automated Multi-Region replication, AWS Managed Microsoft AD handles inter-region networking, deploys domain controllers in separate Availability Zones per region, and replicates all directory data including users, groups, Group Policy Objects, and schema. The service configures an Active Directory site per region to optimize authentication performance and minimize cross-region data transfer costs. Multi-Region replication is available in [AWS Opt-In regions](https://docs.aws.amazon.com/directoryservice/latest/admin-guide/regions.html) where AWS Managed Microsoft AD is available, except the Middle East (UAE) and Middle East (Bahrain) Regions. You pay by the hour for the domain controllers in each region, plus the cross-region data transfer. To get started, see the [Configure Multi-Region replication guide](https://docs.aws.amazon.com/directoryservice/latest/admin-guide/ms%5Fad%5Fconfigure%5Fmulti%5Fregion%5Freplication.html).
