Dedicated servers are nice, but I'm looking for something different, inexpensive and relatively new. That's when I've come across cloud hosting technology.
Rackspace provides Cloud Server hosting for a relatively low price, and I've been considering reselling game servers to my own personal clients.
However, my main concern is the reliability of such a game server. Would the server run properly, would it cause fps lag? Would it even run at all?

Thanks.
