I've been trying to get to the bottom of this and can't find the real definitive answer anywhere. Personally, I'm leaning towards Azure AD is a SaaS service like Exchange Online. This is because your able to control and configure AD, but not Domain Controllers, FSMO Roles, Replication, extending the Schema, etc. (that is if Azure AD has them like AD DS). However, I also believe Identity Management and Authentication is a REQUIRED feature and service to any system, which should sit in the Infrastructure side. This is why I also considered Azure AD to be a combination of both. What say you all....?
Microsoft Entra ID
A Microsoft Entra identity service that provides identity management and access control capabilities. Replaces Azure Active Directory.

Azure AD is a Software-as-a-Service (SaaS). IaaS would imply that you can host your own services on Microsoft/Azure's AAD infrastructure (which you can't). Another point is you have 0 patching to do. In a IaaS environment, you are responsible for patching and upgrading software. Microsoft takes care of this for you and you don't have to know any thing going on behind the scenes.
For more information on Azure Active Directory you can read:

If this is helpful please accept answer.

2023-06-10T16:59:28.77+00:00 That's what I thought! I just wasn't able to find the definitive answer. Also, I really like how you distinguished the difference between SaaS and IaaS, which is patching and upgrading. It never occurred to me to think of that. Thanks!
