Lambda does get expensive when call volume goes up. If you're handling 10rps typically, ECS becomes a lot cheaper. It obviously depends on how long your request last but still. As for running it locally, it depends what your upstream is. I can tell you that I've had to work around bugs in the marshalling from MSK for example. You would never find that locally. If it's just web requests, sure.
