Thoughts and talks on continuous delivery, devops and software development
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!
This amazing photo was taken by Chris Heijmans in 2012. Last year, I ordered a canvas print, which is now proudly displayed in my home. Admittedly, current conditions (partly cloudy, windy, 8 degrees celcius) are nowhere near what’s pictured, but one can hope 😉
2016 has been interesting! I’ve met loads of cool people and been part of some amazing projects. Thank you for reading this blog, attending my talks, following me on Twitter, or listening to me advocate (rant?) in person.
From my cozy, little hometown Utrecht I wish you and yours happy holidays, see you in 2017!
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”.
Below are the slides of my talk “CQRS & Event Sourcing in the wild”, as presented at ScotlandPHP 2016.
A few months have passed since the last Phing development update, so it’s about time to discuss some of the recent changes.
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
In this post I want to talk a little about concurrency in the context of CQRS and event sourcing. Specifically, when a single aggregate is concurrently accessed by two commands (or command handlers, really). Read more
