That doesn't really solve the problem, it just moves it. If AMIs are your deployment method of choice, you still need to build a repeatable process for applying updates and changes to your previous base AMI, testing that it still works under all your realistic configurations, and then gracefully deploying it to your production infrastructure. Which is all doable, but not trivial. And the processes you build will be very Amazon-centric.
