Load Balancer?

[venon]

trying to understand.
OK my website is growing fast and trying to stay ahead by planing what to do next when one server not enough.


i been planing to get 2 server just to run my site and already using litespeed load of the server so far still good after have my server tech optimize sql and a few things more.
average load is 3 and thats with 750 members online .
actual server is a quad core 2.4 with 4gb ram using litespeed 4 cores.
and we use vbulletin .

my site is expected in few months to have a average of 5000 members online at same time(some days).Because of this i been research on what should be next step.



how Load Balancer works ?
do you need 2 or 3 server for that ?
what the best setting to have ?
can all this be accomplish with one server?

You can use two servers for the load balancing setup.
On one server, install both litespeed web server and litespeed load balancer, another server only install web server, the DB can be on that server or have a dedicate DB server.

Let all traffic go to the server with load balancer, load balancer will distribute requests to web server on the same server and to the second web server box.

We have a customer using the same exact setup.
