I'm not so sure. I can see a single point of reference for many apps, but I suspect there may be interfaces or proxies built that push some of this stuff to a cloud environment. Why not use a cloud if you can firewall access to it from the corporate network only and save on the need to manage your own machines. Why not use it in places for non financial/PII/medical information? I could see lots of small departmental apps moving. For that matter, I could see all kinds of quick analysis stuff moving because it's easier or quicker to throw something up in a cloud environment if your IT group isn't responsive.
