AWS Directory Service now lets you dash a Microsoft Active Directory (AD) as a managed service. AWS Directory Service for Microsoft Active Directory (Enterprise Edition),also referred to as Microsoft AD, is powered by Windows Server 2012 R2. When you select and launch this directory type, or it is created as a highly available pair of domain controllers connected to your virtual private cloud (VPC). The domain controllers dash in different Availability Zones in a region of your choice. Host monitoring and recovery,data replication, snapshots, and software updates are automatically configured and managed for you.
Microsoft AD enables you to dash directory-aware workloads in the AWS cloud,including Microsoft SharePoint, custom .
NET and SQL Server-based applications. You can also configure a trust relationship between Microsoft AD in the AWS cloud, and your existing on-premises Microsoft Active Directory,providing users and groups with access to resources in either domain, using single sign-on (SSO).
