Puppet
From Indie IT Wiki
Introduction
Puppet, from Puppet Labs, is a configuration management tool that helps system administrators automate the provisioning, configuration, and management of a server infrastructure. Planning ahead and using config management tools like Puppet can cut down on time spent repeating basic tasks, and help ensure that your configurations are consistent and accurate across your infrastructure. Once you get the hang of managing your servers with Puppet and other automation tools, you will free up time which can be spent improving other aspects of your overall setup.
