So what was my motivation for this?

Well the Rackspace Cloud Management Console is severly lacking in features. Things such as creating an image of a server (just like you can in AWS EC2), and sharing an IP address between servers (something you cannot do in EC2 – an IP address can only be attached to a single instance at a time). It is this second feature that I am most interested in because it means I can use a virtual IP address (floating IP) to create a HA (highly available) “cluster” of Tomcat servers. I plan on using keepalived to do the IP switching, and Apache with mod_proxy_balancer and mod_proxy_ajp to talk to multiple Tomcat servers. Without reading the poorly written API documention and learning that I could create a shared IP group, I would not have known this was possible.

This project is very much a work in progress, and what is in there now represents only about 8 hours of work. I welcome any feedback, and anyone else who wants to join.
