You may already know Azure Active Directory Domain Services (AD DS), the Azure feature allowing you to host your Active Directory Domain Services on Azure.
Well, until now, this Azure AD DS capability was only available for User Forest mode (aka hosting active user accounts).
Good news, you can now also provision your Azure AD DS as a Forest Resource.
The principles here are exactly the same as the ‘classic’ User/Resource Forests deployment on-premises.
Enjoy this new Azure AD DS capability.
