I will give it a try. We have been playing around with ultramonkey
and mod_proxy_balance.
mod_proxy_balance should also be part of the above mentioned package,
but for reasons
of platform indepence and features like failover we implemented a Java
version.
What was your experience re ultramonkey and mod_proxy_balance?
We are using a "High Capacity High Availability and Load Balancing"
ultramonkey setup
(http://www.ultramonkey.org/3/topologies/hc-ha-lb-overview.html). Our
"real servers" are running a slimmed down apache2.2.x. We are using
them as our http accelerator using mod_proxy, mod_proxy_balance,
mod_cache. We are balancing our tomcat instances (and other service
clusters) with mod_proxy_balance.
We are still testing and tweaking our config, but it appears to be a
very robust/scalable solution for us. It is cool giving the demo and
being able to unplug half of our servers and still be able to access our
services. We are next going to see if we can split our cluster(s)
between two buildings for the sake of disaster recovery. We could have
a fire/flood and our web will still be up.
