Use managed domain services on Azure
Use Azure Active Directory Domain Services to join Azure virtual machines to a domain, without having to deploy domain controllers. Sign in to the virtual machines using their corporate Azure Active Directory credentials and seamlessly access resources. Use Group Policy to more securely administer domain-joined virtual machines—a familiar way to apply and enforce security baselines on all of your Azure virtual machines.


Migrate on-premises apps to Azure with no identity worries
Take advantage of Azure Active Directory Domain Services features like domain join, LDAP, NT LAN Manager (NTLM), and Kerberos authentication, which are widely used in enterprises. Migrate legacy directory-aware applications running on-premises to Azure, without having to worry about identity requirements. On Linux and Windows Server virtual machines on Azure, easily deploy line-of-business applications. You don’t have to deploy domain controllers as Azure virtual machines or use a VPN connection back to your identity infrastructure.
