The Road to Continuous Deployment (part 1)

The story below details a very interesting & transformational project that I was a part of in 2014 and 2015, at a Dutch company. I’ve told this story before during a number of conference talks (slides and videos are available, if you’re interested), and I’ve now finally come around to writing it up as a series of blog posts!

State Of DevOps Report

The 2017 version of Puppet’s State of DevOps Report was just released.

To me, the most interesting takeaways from the report are:

  • High performing teams have 46x more frequent deploys, 96x faster mean time to recover/repair and a 5x lower change failure rate.
  • They also automate significantly more work (automation is a key ingredient of any successful DevOps strategy).
  • A lower change failure rate and significant automation mean these teams spend 44% more time on new work (and 26% less time on unplanned work and rework).
  • Developers in high performing teams generally work in small batches and practice Trunk Based Development. Low performing teams on the other hand use long-lived feature branches and merge infrequently to trunk or master (read on for my thoughts about feature branches).
