time goal: 40 minutes.

Abstract

Puppet is a tool for doing configuration management. This talk will go over what puppet is, what it can do and how to do it. There is more than one way to do it, some lessons have been learned in the field and from the community. The talk will be based on Alessandro Franceschi's fine http://www.example42.com/tutorials/PuppetTutorial/ . Note all slides will be discussed (developer oriented slides) , and some topics not mentioned in the URL will be added (work flow topics). I intend for this talk to be a dialog and support "engaged" learning, feel free to interrupt.
