I've got a client who wants to move his companies servers off site. As he is only a 10 person company I'm looking for some pretty in-expensive options. One option is the smallest of the Amazon cloud machines. The question becomes can I make one of these machines a domain controller?
Cost wise the Amazon machine is cheaper than the power costs of keeping a server (or a PC) up and running in his home office 24x7 thanks to the high cost of power in Southern California.
Yes, but I think that's a pretty bad idea. There are all kinds of problems that you can have when you lose access to a domain controller, so any network interruption will have huge business consequences. You'll have to have some kind of tunnel to secure it, a WAN...
Are there no servers in the building? Not even a file server? You don't need a lot of horsepower to run a small AD domain.
This question deals with the nuts and bolts of making it happen.
