I am wrapping my head about how much infrastructure you can put in the cloud. Can you get a room down to just a router and a switch in a building and get your DC's and servers in the cloud? Does anyone have any reference articles on cloud scenerios for IaaS?

I am seconding that question. I have been wondering if I could use the MS cloud to provide a DC for maybe a 5 user office. I would also like to have local storage (for speed) replicated to the MS cloud. All that would be available to the users in their office and at their homes.
I so wonder...what can I do with a local server and azure?
The answer is yes you can...the real question though is should you? probably not. Better idea would be to have an on premises AD and another DC in the cloud in case of failure.
In @Greg-Sanders244, You can replication between cloud and local storage, using something like OneDrive but if you're doing this you're now talking about synchronizing on premises AD to the cloud AD doing same sign or if daring, single sign on. This requires doing AD synchronization between On-Premises AD and Azure AD.
