  • We started small.\n
  • And grew ad-hoc.\n
  • For various reasons Linux got introduced in parts of the solution\n
  • Those Linux nodes where then split out into two main node groups\n
  • The much simplified high level overview of the current solution\n

  • cfengine, then puppet, then chef\n
  • Right from the start it’s pretty obvious what’s being used as far as my network and “research” counts. The long timers started with cfengine and most tend to be on puppet with some on chef. Nonetheless, Puppet or Chef it is.\n
  • At the time of selecting tech we didn’t have the manpower nor the time to learn and introduce any tool ourselves. And we were unable to find anyone who could assist us with Chef - which was our first hand choice.\n
  • Stockholm, I was disappoint.\n
  • On the other hand we did find quite a few people who had experience with Puppet.\n
