Tutorial I gave at LISA 2014 http://goo.gl/G0TLfJ
This is a talk about running puppet in the enterprise, or at scale. The original title of Mastering Puppet was Puppet in the Enterprise, the talk was to present the ideas in the book.
The tutorial files are located on github at: https://github.com/uphillian/lisa2014
