Active Directory Domain Services (AD DS) is a directory service developed by Microsoft that runs on Windows Server. It provides the methods for storing directory data and making this data available to network users and administrators. Enterprises moving their services to the cloud often require AD DS to facilitate global management. For example, an enterprise may want to use AD DS to manage account information and allow other authorized users on the same network to access this information. Alibaba Cloud allows you to configure Alibaba Cloud RDS SQL Server to work with AD DS and centrally manage your directory data. You can store and manage directory information after you migrate your services to the cloud. You can create a logical, hierarchical organization of directory information stored on the cloud and allow authorized users on the same network to access directory information.
