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

I have always wondered how serious load balancing was done :)
Is this technique documented anywhere?
I would love to read up on it.
Thanks

I always wondered about how high-profile sites like Ebay and Amazon
updated their systems because they never seem to place
messages at their
sites regarding system downtime for routine
If you use Resin/J:Rockit/NewISys 2100, you can do at least 4,000
cocurent users w/ sub second response time. (test your app w/ free
DiselTest - part of Jasic and linked on basicPortal.com, other links

NewIsys is a 1U.
A 19 rack can hold 40. You need 3-4 racks.

to another for the next request, how does server 2 get my

any change is made to it?

Angus,
doesnt using a shared jdbc based session manager slow the whole thing down
a lot? Why dont you just use session persistence?

terabytes of disk while
only have 2 GB of memory. Seems to be an easy trade.

Oh OK cool so it is how I thought - presumably you dont use the session
very much (in terms of sending stuff to it) or else there would be one
serious amount of db work!

hi Angus,
from ur reply what i understand is, first I have to develop
the application
(with maximum tuning possible from scripting side) and the
deploy it on a
server and load test
but I had have 2 or 3 terabytes of disk while
only have 2 GB of memory. Seems to be an easy trade.

individually while the other nodes support user requests, or
