AWS Managed Microsoft AD enhanced its Multi-Region replication by enabling automated synchronization of directories in Opt-In regions, removing the need for manually managed independent directories. This supports domain-joined workloads with consistent directory data including users, groups, and policies.
The service automatically deploys durable domain controllers across Availability Zones and configures Active Directory sites per region to optimize authentication while minimizing cross-region data transfer. This feature is broadly available except in specific Middle East regions, with usage priced hourly plus data transfer fees.
