Subject Re: how to suppor 30000 concurrent users
Date Fri, 02 Aug 2002 13:21:18 GMT
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. then add the needed number of servers. have  i got it
right?
what is an avarage no of maximum concurrent users (active sessions) for
tomcat (just to get a general idea about the possible investment)

does it depends on the scripting technology also? how is  Microsoft
technology is such case (heavy load) compared to tomcat?
thanks and regards
Prince

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 :)
