With that many users you are going to HAVE to cluster if for no other reason than to provide backup for system maintanence. As to how many, the answer is it depends on the hardware you are going to use and the types of load your webapp puts on the system. When you say 30k concurrent users do you mean 30k people clicking a link at the same time or 30k active sessions at a time? If you are going to have this many people clicking on the same time you should have the cash to do proper load testing to see how many people one of your servers can take, divide 30k by that number for the number of servers you have, multiply by 1.1 AT LEAST and round up to get 110% capacity so you should be able to swap out one server. This is BARE minimum. Don't forget about the wonderful world of DB backends and routers and all the fun stuff :) --Angus
