I currently have a small network with a few servers and about 25 client PCs. We are using Office365 and have AD synchronisation setup from our on-premise server. We also have single-sign-on setup using ADFS.
We have recently replaced all but 2 of our servers with Azure virtual machines.
The only thing we now use our internal servers for is the Active Directory and ADFS.
So - my question is this... Can I setup an Azure Active Directory, sync my on-premise directory to it, get Office365 to talk to the Azure Active Directory and then decommission my on-premise servers?
Will my local client PCs authenticate against the Azure Active Directory?
If the answer is, "Yes" - any suggestions for how to achieve this would be great. If the answer is, "No" - some information on why not would be great!
