Deepak's "archetecture" document shows /way/ more hardware and sofwtare
than is necessary.

Since there's already a single point of failure (the topmost Apache
httpd instance), you may as well use that to directly load-balance the
bottom-most Tomcat instances. That eliminates 6 of the 10 logical
servers in your diagram without, IMO, any loss of capability.

It will certainly improve performance, too, without all that needless
re-proxying.
