Building Hybrid network on Azure is it possible?
<p>I need to build a hybrid Azure cloud network moreover it will be used as a failover network. I will tell you the scenerio let me know is it possible.
I have 5 sites lets name it A, B,C,D and E. Site A is the main site and it has Primary Domain Controller Server , DNS Server.
Site B and Site C has only Domain controller.
Site D and E have no servers at their location and they are dependent on Site A for AD authentication.
Every site has ReadyNAS which uses AD authentication.
So now the situation is if Site A goes down completely then the Site B and C can communicate with their local NAS drives as they have Domain Controller in house and it provides AD authentication. But site D and E are unable to it because they are dependent on Site A so to remove this dependency I thought of building a failover network on Azure such that I will have one DC server on Azure which is in sync with DC servers on site though VPN and if the site A goes down the site D and E still get authenticated from DC on Azure and they could access their local NAS drives. I just wanted to know is it possible in real life and what configuration changes on AD sites.</p>
