Doesn't matter what you use for front end. Ruby used to be a POS VM in terms of performance, but who knows now a'days, but just about anything can return json, so just grab what you can.

Your real pain point is going to be your back end. If immediate consistency isn't important, run a job queue with works in the back end hitting some kind of fast access nosql and have a worker whose job it is to write to a mysql or postgress store. raid the ebs volumes and keep a monolithic volume sister box to take snapshots off. you can have the entire environment scripted and repeatable.

I asked ravaa to stop by and give his .02. He's well versed in the world of infrastructure and I highly value his opinion.
