according to Hardware Recommendations I can support up to 10,000 concurrent users with a simple dedicated server which will costs me something like 4000$ per year(300$/m). The enterprise edition will cost me 15$ per registered user (not concurrent???) and can sum to more than 150,000$/year. Obviously I get the web client and the other features of the enterprise edition. It just doesn`t make sense. Can any social network with 10,000 users spend 150,000$/year just for IM?
What am I missing?
