Tomcat Farm Recommendation
I'm trying to move my Apache Http Server Farm to a Tomcat one and I guess
that Tomcat needs more resources than Apache does. Our approach has been
always to have many medium size machines than a few big ones, does anybody
have any suggestion to the kind of machine + OS needed to get the best
tomcat performance?
Thanks,
Johann

Thanks, I have to still trying to convince some people that Tomcat can
perform without a lot more of resources than Apache Http Server does.

there is no right or wrong solution, but entertain this scenario
1. few very large machines (or)
2. many very inexpensive machines
in the case of one machine breaking, using 1) will have a larger impact
on your performance than 2)
however, in the case of 2) you may have more failures.
take google for example, in an article by their CTO I read they are
essentially using option 2), because it is so easy/quick/cheap to replace
however, remember that using 2) also usually has much more power
consumption, so if power cost is an issue, you will need to setup a
matrix for yourself.

Thanks for your reply, I know that there are a lot of things to consider to
give this kind of answer but my question was more about what do you have
that has worked for a corporate site, we're going to have mostly stateless
RPC Servlets for a Client Side RIA (GWT) and our scope is millions of users
pero month.
Thanks.

First things first, I do not have an answer. As for the approach of multiple
machines it does allow for better fault tolerance. But is also has the
disadvantage of multiple machines to manage. And I am sure the list has lots
of other pros and cons. As for the machine brand selection is another area
of debate that can go for days. I would recommend a brand you are
comfortable with and can get hardware support. As for processor and memory
these are really dependent on your application and user load. If you have
some base numbers to work from you may get some guidance from the list. For
OS you will find that there are supporters from many different camps. Again
this is often a case of what you are comfortable with. If you search the
list there are some links where comparisons have been made with different
OS.
Memory: How big is your app? How many apps? How many users?
Processor: How many users? How much calculating(processing) in you apps? How
many apps?
OS: Is it supported with a current stable java environment? Cost? Platform
requirements?
