Stuff I learned about Puppet

Chef vs Puppet

• My blink is that in 2012 Puppet is safer and more productive.
• Puppet is declarative, Chef procedural.
• Puppet brings system into compliance (state), Chef "does" things (recipes).
• Puppet has strong security practices; Chef has a toleration for loose security in Chef itself.
• Puppet makes it very hard to get "outside the lines" or violate its strong opinions; in Chef this is routine.

• You would like to deploy your application using RVM, Capistrano and Bundler
• Your application source code is hosted on a remote GIT repository

Update the operating system
