AWS Directory Service to Microsoft Active Directory, also known AWS Managed Microsoft Active Directory (AD), allows you to use managed Active Directory in AWS with your directory-aware workloads. AWS Managed Microsoft AD is based on Microsoft Active Directory and does not require that you synchronize or replicate your data to the cloud. You can use the standard AD administration tools, and you can take advantage of the built in AD features such as Group Policy or single sign-on. AWS Managed Microsoft AD allows you to join Amazon EC2 or Amazon RDS for SQL Server instances in your domain and use AWS End User Computing services (EUC), such as Amazon WorkSpaces with AD users and groups. AWS Managed Microsoft AD makes it simple to migrate AD-dependent Windows workloads to AWS. AWS Managed Microsoft AD allows you to use Group Policies to manage EC2 instances, and run AD-dependent apps in the AWS Cloud.
