Thanks for helping me out guyz but w're already dealing with 3-app servers
clustering with haproxy load balancer (For this video streaming site), and
can't afford another clustering type things. You're talking about Haproxy
load-balancer to split required flv files requests to different servers.
We'll have to buy 5 more content servers for mirroring data between every
two servers to split load-balancer requests but the problem is we're
running out of budget. If you can provide me some alternate to this problem?
