Learn how the event-carried state transfer pattern can help you build powerful event-driven systems and what pitfalls you need to be aware of. — In the third blog of the ‘engineers guide to event-driven architectures’ series, I discussed the most commonly applied event-driven software design pattern, the event notification pattern. Let’s explore an alternative pattern to use, the event-carried state transfer pattern. In this blog, I explain the characteristics of the pattern, how this…

Learn how the event notification pattern can help you build event-driven systems and what pitfalls you need to be aware of. — In the second blog of the ‘engineers guide to event-driven architectures’ series I discussed key concepts to designing and implementing a successful event-driven architecture. One of those is building knowledge on commonly used event driven software design patterns. And there’s plenty design patterns to discuss, but it seems fitting to…

In the first blog of the ‘engineers guide to event-driven architectures’ series we discussed how event-driven architectures can deal with complexity, how it provides agility and that there is massive scaling potential. It is my personal belief that every solution architect and software engineer looking to solve challenging problems at…

Many big technology companies like Netflix, Uber and Spotify have moved from a monolithic architecture to a microservices architecture in order to successfully build and run complex systems at a massive scale. Event-driven architectures are becoming increasingly popular in the microservice space due to the scalability potential as well as…

At the beginning of the year, before the human malware breakout, an Italian engineer joined our team straight from university. She has a superpower. Randomness. Along the way I realized just how important randomness is in learning and building a team. …

Let’s face it. Java is an ancient language that is struggling to stay relevant but is not suited for containerized microservices due to its big resource footprint and limited concurrency. Java is trying to catch-up, but was clearly late to the party. So late in fact that everyone already left…

There is a lot of things I like about Java, but its dated implementation of threads is challenging to work with when developing high-traffic microservices. …
