Thanks - the 120K users is more likely the total number of users for the app - so chances are slim of them all using the site at once - but want to plan for the worst. Might be putting together a license deal and just want to make sure that I don't bankrupt myself. So - a metric might be 30 concurrent users for 4 mongrels - 4 mongrels per EC2 server. 120 CCU would be 16 mongrels on 4 EC2 servers, etc. Not that I'd use EC2 - just a convenient constant - load balancing would be tricky.
