What is Puppet?
Puppet is an open-source next-generation server automation tool. It is composed of a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration. The primary design goal of Puppet is to have an expressive enough language backed by a powerful enough library that you can write your own server automation applications in just a few lines of code. Puppet’s deep extensibility and open source license lets you add functionality as needed and share your innovations with others.
