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.
