The keepalived daemon provides this. Can be triggered manually
(I'm doing this for a master-master mysql setup) or automatically,
for our "backend" LVS system.
This is achieved b

There's a heartbeat system you can use for HA. If you look at the
docs for LVS you'll see info on it.

What are you guys using to cluster the LVS servers? Is that
functionality native to LVS?
Also, I've come across "fastcgi" a lot in researching this and I'm
having trouble understanding exactly what it is.
The fastcgi website makes it sound like it's almost a mod_perl
replacement and another

LVS does sound interesting but in your infrastructure layout aren't your
single LVS load balancers single points of failure? Especially if they
are running on older hardware? Maybe that isn't important in your
environment? However, it seems like that negates a lot of the "high
availability"
I concur with LVS. I have LVS running on a $10 piece of hardware (300
MHz CPU,
128MB memory) that acts as a load balancer for 15+ web servers. I use
keepalive
to monitor the systems.

Hi Brad,
we're using LVS (http://en.wikipedia.org/wiki/Linux_Virtual_Server),
and I find it very useful and reliable.

So it sounds like Apache is simply not going to meet my needs. In the
event that I do need to replace Apache, hopefully you can save me some
research time and recommend me one of the listed options that fulfills
my needs (or confirm that perlbal does)
I need the following features:

Thanks for the recommendations. Puppet/cfmanager look like they are
along the lines of what I'm looking for.

Hello
I have a lot of experience in large scale web applications using Java
and Websphere, but I now find myself needing to scale a web application
built on mod_perl, and I have some questions about best practices for
doing that since I don't have any sort of deployment manager or an
