Other place where this is great is enterprise cloud migration and hybrid cloud formation. When one decides to go cloud, you need to throw away you prior investment in SO licenses and hardware. Although you have no alternative but throw away hardware, being able to reuse investment in software greatly reduce migration costs. Of course one can just wait until all his licenses expire and then migrate, but such a hard migration would increase risks. And of course it would be nice to have a price comparison between running normal instances and using a dedicated host with my own licenses, but without deeper inspection, dedicated is cheaper.
