I think there is always going to be some amount of overhead with physical or cloud services for scaling. I can say though that one thing you can do with physical servers which is pretty neat is shut down entire physical nodes when you don't need them to save on resources. Your scaling software has to know how to do this, but IPMI is fun stuff like that.
