Re: Would this work? (Load Balance Question)
We do that, with a firewall in front of the Apache, and one behind it, in front of the TC and DB. BTW: It works ;-) Antonio Andreas Mohrig wrote: Dave, although I have never set up such a configuration, I have thought about it quite a lot.

It is even quite attractive from a security point of view, because neither your tmocat servers nor your database-server get any chance to expose some services/ports to the whole wide world (provided you disable routing on your webserver). Of course you would need a switch on the internal network, but that could even be a gigabit-switch to remove at least one bottleneck.

Re: Would this work? (Load Balance Question)
Yes. And that is a prefered way to set things up.
