I have three sites where the client does not want to incur the management of physical servers. They would rather push their AD to the cloud. Currently they do not have AD just three sites with a mix of WIndows 7 Pro workstations and no central management.
Based on the diagram I have attached, has anyone setup up anything like this? Azure documentation says that on prem DNS and AD is needed. I am trying to do it without this and all over a site to site VPN connection.
