I do agree that Chef [and RightScale? Never used it) makes it easy to spawn new instances and through load balancing average your load.
I was talking in term of tradeoff in the first few weeks of a new service with a MVP. Obviously, you re-assess your need before you get to 100k user, and probably uses something else than EC-2.
In any case, both ideas are equally good. I don't claim better knowledge in any way.
