Announcing new Apache Tomcat installable Live CD appliance
Hi everyone,
I'm one of the developers for TurnKey Linux, a community oriented open
source project developing a family of free, Ubuntu-based installable
Live CDs which are lightweight and optimized for ease of use in
server-type usage scenarios (e.g., LAMP, Joomla CMS, Drupal, Ruby on Rails):
http://www.turnkeylinux.org/appliances
We're proud to announce the release of TurnKey Apache Tomcat, an
installable live CD of Apache Tomcat that can run on real hardware in
addition to most types of virtual machines (e.g., VMWare, VirtualBox,
Parallels, Xen HVM). It is designed to provide users with a
pre-integrated, auto-updating, turn-key operating system environment
that is carefully built from the ground up with the minimum components
needed to run Apache Tomcat with maximum usability, efficiency, and
security.
Basically this is an extremely easy way to get up and running with
Apache Tomcat in just a few minutes.
Feature highlights:
* Auto-updated daily with latest security patches
* SSL support out of the box
* Elegant Web administration interface (Mac OS X themed)
* Minimal footprint (212MB)
Full details: http://www.turnkeylinux.org/appliances/tomcat
BTW, this type of pre-integrated, ready-to-use system is typically
called a software appliance:

Take a look and tell us what you think!
Cheers,
Liraz

That's sort of why we posted to tomcat-users. We're not Apache Tomcat
experts ourselves, so we figured the community would have some good
feedback on our first stab at a Tomcat appliance.

Ah. We seem to have been misinformed.

Thanks for the feedback. Really, this is exactly what we need to improve
the next version.
If anyone else has any feedback on our beta appliance or good ideas for
the next version, speak up!
Cheers,
Liraz

If you are really looking for a useful load-balanced appliance check
for keepalived or pound.

Sounds good!
Don't get me wrong: I hadn't intended to merely complain. I'm just
applying some of the best practices I've learned through the years both
working on my own projects and helping out folks on this list. I think a
Tomcat appliance is a great idea.
Remember to use APR for SSL! :)

Quite right. We forwarded some of the feedback we received on the list
to some of the people consulted with and it seems there was a
misunderstanding on our part. It doesn't make sense for the load
balancer and Tomcat to be in the same appliance. We'll be fixing that in
the next version.

I would argue that "A" is best achieved by a hardware load balancer
rather than Apache httpd, "B" is actually /not/ achieved by the addition
of Apache httpd (more components means more complexity which means
higher maintenance costs), and "C" is served perfectly by Tomcat alone.
If I were you, I would provide a Tomcat-only "appliance" and a separate
"load-balancer" appliance that could be trivially combined to achieve
all your goals.

You're right Chris, you don't _need_ Apache, and therefore mod_jk to run
Tomcat. Tomcat can listen (and does by default, though we turned it off
for security reasons) and answer requests directly.
OTOH, we consulted with a few Java people who told us you usually (in a
production setting) want a load-balancer (eg. Apache) in front of your
Tomcat node[s] to:
A) improve performance
B) make the setup easier to maintain
C) provide a way to serve static content
In the future we might create a more minimal Tomcat node appliance to
which a front-end load balancer appliance could offload traffic, but
that needs more thought...
Cheers,
Liraz

If your goal was a minimal set of components, why did you choose to
include Apache httpd + mod_jk, neither of which are required to run Tomcat.
