Cloud computing is a good fit as long as your applications are not deeply embedded and entwined. Essentially if you are able to quickly and easily duplicate and move server and network setup. We hadn't developed appropriately in the past for it, but we are now. I wouldn't exactly say we are properly DevOps oriented, but we're a lot closer to that with what we put together these days, and hence I can't see us moving away from Cloud based systems now.
