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!
Continuous Deployment
PHP UK Closing Keynote (video)
Last month the good folks at the PHP UK Conference asked me to host the closing keynote. So, on Friday February the 22nd, I took the audience on a journey through my experiences with and views on Continuous Delivery and DevOps.

In 2016 and 2017, I gave a series of talks titled “The Road to Continuous Deployment: a Case Study”, detailing some of the work I did in 2015 together with the team at De Persgroep Employment Solutions. At DPES, we significantly improved time to market, quality and delivery speed by implementing Continuous Delivery. In the talk I explain how the process took us to multiple production releases per day and how we significantly changed and improved our way of working. This blog post reviews a (short) version of that talk, as given during the first online All Day DevOps conference, in 2016.
A typical CI/CD pipeline explained
Recently, I was asked on Twitter if I could give some pointers for reading material on (production) CI/CD pipelines – what they look like, and how they work. I decided to shed some light on this by describing a typical CI/CD pipeline (from my perspective), in a series of tweets. This article is an expansion of that thread.
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).

Training sessions and talks
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!
The Strangler pattern in practice
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.
