iJUG-Magazin Java aktuell – Performance Tests of Microservices

Load and performance testing is not trivial. Load and performance testing microservices is even more challenging. Our article “Performance Tests of Microservices” in the iJUG-Magazin Java aktuell talks about approach and challenges when designing and executing performance test for microservices. So get yourself the Java Aktuell or, if you just want to check out the article, use this link to the PDF and enjoy. The article is in German.

A software architecture that consists of small independent components, is easier to create and to maintain. As a result of that, microservices have turned into a dominating topic in terms of modern software development. While the complexity on the development site is decreasing, topics like architecture, performance, such as the planning of performance tests and reliability issues of microservices are getting more attention. This article discusses the performance requirements and performance test planning of microservices.

The days where Java was considered a slow bytecode interpreter have ended a long time ago. JVM is using many tricks in order to execute a code efficiently and to transform and optimize a Java code on the used hardware. With some knowledge about these processes, you can avoid working against the JVM system, while achieving more speed. Even if you are not chasing every last microsecond, it is still interesting to see what methods and techniques JVM uses for a better understanding of the runtime environment.
