AZURE AD DOMAIN SERVICES – AADDS

Azure AD Domain Services is an entirely new concept. It’s a cloud based service which gives you a fully Windows Server Active Directory compatible set of API’s and protocols, delivered as a managed Azure service. This means as part of Azure AD you can now turn on support for all the critical directory capabilities your application and server VM’s need, including Kerberos, NTLM, Group Policy and LDAP.

Azure AD Domain Services has two approaches:

1. Cloud only Organization – Azure AD Domain Services in Cloud without on-premise identity footprint:

2.  Hybrid cloud AD organization – Azure AD Domain services synced with on-premise AD using the Azure AD Connect.

More details of creating the Azure AD Domain services with existing Azure AD tenant and enabling the Hybrid Azure AD cloud. Please refer the below url.
