One of the features of the Spring Framework is a cache you can transparently add to your code. All you need to do is set an annotation on a method you want to cache and configure the caching mechanism itself.

28.08.2017 by Jens in Spring Boot | Spring Data

In my Spring Boot workshop last week one of the participants asked me to clarify what Spring Data actually is. He came from a different background and was confused how Spring Data, JPA, Hibernate and NoSQL relate and what role Spring Data plays. Indeed, if you switch contexts, it may look strange at first. However, it is not, and I write today the same I answered in the workshop.

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. I was baffled but it seems there's a lot of confusion what Spring Boot actually is and when to use it. This article does shed some light on it.
