ruby gem to easily bootstrap a multi server application all you have to do is define the servers that you need with a yaml file and cloudbuilder will create the servers on the desired cloud
note, all the servers do not need to be on the same cloud
one of the main uses of this is to allow developers to easily create a developer or staging version of their production application
a deployment tool that can be used with puppet or chef scripts
The idea for cloudbuilder was borne out of a furstration between using vagrant locally on my developer machine and then trying to deploy the application to a cloud
