Azure Active Directory Domain Services pricing

Domain services for virtual machines and directory-aware applications

Azure Active Directory Domain Services provides scalable, high-performance, managed domain services such as domain-join, LDAP, Kerberos, Windows Integrated authentication, and group policy. With the click of a button, administrators can enable managed domain services for virtual machines and directory-aware applications deployed in Azure Infrastructure Services. By maintaining compatibility with Windows Server Active Directory, Azure Active Directory Domain Services allows administrators to easily migrate legacy on-premises applications to the cloud and to centralise management of all applications and all identities in Azure Active Directory.
