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).

One of the things I like most about my work is the ability to help teams improve, by sharing my experiences and knowledge in training sessions. These sessions can be conducted in the form of interactive workshops or talks.
I’m offering training sessions on DevOps, Continuous Delivery, Event Sourcing, Microservices and many other topics. Contact me if you’re interested in details or pricing!
In this post I’ll discuss my experiences with the strangler pattern and how it can be applied when rewriting a large, legacy code base.
In a little less than two weeks, on Tuesday November 15th, I’ll be speaking at All Day Devops. A free, online DevOps conference spanning 15 timezones with 50+ sessions.
Join me at 10 AM GMT for my session “The Road to Continuous Deployment”.
Recently I was asked for books and other literature recommendations on the subjects Continuous Delivery / Deployment, DevOps and Microservices. Here are some of the books, articles and talks I think are worth consuming.
Below are the slides of my talk “The road to continuous deployment: a case study”, as presented at PHPCon Poland in October 2016.
It’s a situation many of us are familiar with: a large legacy application, limited or no tests, slow & manual release process, low velocity, no confidence…. Oh, and management wants new features, fast.
But how to proceed? Using examples and lessons learned from a real-world case, I’ll show you how to strangle the legacy application with a modern service architecture and build a continuous deployment pipeline to deliver value from the first sprint. On the way, we take a look at testing strategies and various (possibly controversial!) tips and best practices.
“Don’t use branches”. Three words that are guaranteed to trigger reactions when I utter them during my continuous deployment talks. Three words that make for interesting discussions. This post contains some of the arguments I use during those discussions. Read more
