Switching load or transferring data between a remote DC (your dedicated servers) and AWS is not that easy when you start having large-scale infrastructure though. This is a great idea on paper - but running your baseline infrastructure at your dedicated provider and the rest on EC2 is definitely a challenging task. Not that it's impossible, but that's probably going to be extra work at the app level. --- Running OpenStack / CloudStack, or similar software on dedicated servers is indeed a relevant solution too, but this is an extra maintenance cost to bear in mind.
