Why You Should Think Twice Before Even Considering Polyglot Microservices

22.07.2017 by Jens in Developers Life | Learning

Microservices can be a good solution for a particular problem. But, sometimes they are not a good fit. One of the aspects involved is that developers praise the benefit that you can develop every service in your landscape in a perfectly fitting tech stack for a given problem. Honestly, this can become your worst nightmare, so I will cover why you should think twice about this before going that route.


Is Spring Boot for Microservices only?

12.07.2017 by Jens in Spring Boot

Last week I was chatting with a friend and he told me how lucky he is that a part of their system moved to using Spring Boot. It made his life easier with development and testing. He actually loved writing tests now. However, one of his colleagues did question the decision to go with Spring Boot because Spring Boot is meant to be used with Docker and for microservices only.

3 Learning Mistakes Developers Make

14.06.2017 by Jens in Developers Life | Learning

Learning can be fun or hard or maybe both. For me, it’s often a mix of both. I developed my own learning style over many, many years. It usually works well for me and I pick up new topics, be it a new programming paradigm, language or business stuff, pretty straight forward. However, when I tried to learn some basic Japanese last year, I forgot everything and made some common mistakes again.


Should I learn Spring or Spring Boot is the Wrong Question

01.06.2017 by Jens in Spring Boot | Learning | Developers Life
