I will explain everything that is happening. I work in a NGO, and we have our office inside a university here in Brazil. Until a couple of weeks ago, our internet infrastructure worked something like this:
- The university receives the internet connection
- Their servers communicates with our Windows Server, which controls AD, DHCP and User Auth
- The answer goes back to the their infrastructure and authenticate the computers connected to computers inside our office connected to their cables/wi-fi
Last week our server went down, and the company that provides us the support is very slow. So I tried to find different options of what to do, and could be easier to maintain, and cheaper than the support we have. What I thought was to use and Amazon EC2 Windows Server to be in place of our old server, therefore the university communicate with EC2, then authenticate the connected computers.
From a research we've made here, this should be possible, as long that the university connection to the EC2 is made on a VPN. My questions are:
- Is this really possible?
- The EC2 AD, DHCP and User Auth configuration would be the same as the local server we had?
- The guys from the university are asking us how things would change for them. Would it just be that now they should use a VPN connection to an outside server, and not a local server inside their network? Or other changes would imply?
Thank you all in advance for the help :) Ps.: let me know if something is not clear!
