How Cloud computing will drive Enterprise Integration

In a few recently witnessed presentations it was extraordinary to see how two utterly unrelated matters were seamlessly joined together on the same slide

I'm talking about virtualisation and Cloud computing on the one hand, and world-wide-web services on the other hand

These two entirely different worlds (physical iron infrastructure versus logical business functionality) have been more often associated together over the last months, but it seems to be getting a bit out of hand now

How can physically relocating infrastructure give you fully disclosed backend systems? Of course it can't. It will force you to adhere to a few standards here and there, but that's all on the (rather dull) infrastructural level.
