Don’t let Architecture Astronauts Scare You

This is not so much a typical blog post. It’s copying a 19 year old post and replacing the technology terms in it with more recent ones. The entire point is just display how we ware still failing to solve real-world problems with “hip” technologies.

Service Integrations

Wednesday, June 5th 2019

Since some months the QAs of ThoughtWorks Germany are witnessing micro service integrations via a shared file storage. What seems like an anti pattern of the 90s is sometimes even enthusiastically embraced in the wake of AWS and their S3 buckets under the umbrella of data science. But is this the correct way to go forward and would that actually help to do data science? We are exploring our thoughts in this post.

Dimensions of Quality

Saturday, December 23rd 2017

One year ago I introduced the “muffin concept” in a small blog post, “how we do Quality at ThoughtWorks”. Ever since then I have been to various Meetups and Conferences to discuss the idea and all the concepts behind it. After another year and dozens of discussion, there are more thoughts around how to bake quality in.
It covers quite different aspects, thus I decided to split this post into a miniseries of 5 posts.

Enjoy the read here and please give me feedback: tell me what you think!

How To: Consumer Driven Contract Tests

Thursday, October 6th, 2016

The guide to testing microservice gives an overview how to test micro services. But certainly, the most complicated step is to test the integration of the services. In the previous blog post I only refer to CDCs, so I want to share more information about how they work in detail in this separate post. It is short and has many pictures, the best way to learn about a complicated concept.
