That, and memory is cheap for ISPs.

There is no general answer to that.
It depends on the structure of the customers that use tomcat.

Just 2 completely different use cases:

You use a fixed set of applications and sell them as a service
to the costomers.

That may be case for one tomcat for several customers.

You sell webspace and let the user do what they wan't
(install applications, upload jsp's, ...)

For me, that's a clear case for separate tomcat instances.

In my experience the raw memory consumption for several 
instances is not the problem (unless you have only webapps 
that have just small footprints). The most part of the 
memory usage comes from the application and this will nearly 
be the same between both solutions.

Depending on what you want to offer you might even have 
different environments for certain user profiles.
One tomcat to serve simple webapps and several tomcats
with one application each for highend customers.

Multiple Server-Users

2004-02-13 Thread Juergen Weber
How do you setup Tomcat for an ISP, that offers Tomcat
services to it's user?

o Have different Tomcat installations for each user.
That would cost lots of memory.

o Put Context configuration XML files for each user to
$TOMCAT_HOME/conf/Catalina/localhost
This should work, but there would only be one context
per user and I am not sure, how good the separation
between users were. I think, one user could grab all
the cpu time from the others. And, how could you
restrict tomcat manager to only one's own context?

What would be best?
Thanks, Juergen
