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.

Performancetests von Microservices

Eine Softwarearchitektur, die aus kleinen und unabhängigen Teilen zusammengesetzt ist, ist einfacher zu erstellen und zu warten. Microservices sind dadurch zum dominierenden Thema in der modernen Softwareentwicklung geworden. Während die Komplexität auf der Entwicklungsseite sinkt, steigt sie in Bezug auf die Themen Architektur, Performance und Zuverlässigkeit. Dieser Artikel diskutiert die Anforderungen an die Performance und die Planung von Performancetests von Microservices.

Comments are very welcome.

Xceptance LoadTest Goes Open Source

We have often been asked why XLT (Xceptance LoadTest) is free but not open source. Now, after considering our customers’ business needs and the advantages of using open source as opposed to free software, Xceptance has decided to open source XLT under the Apache License 2.0.

Within the next 30 days, we will restructure the XLT code base and move subprojects into independent open repositories. We will continue to expand and improve the documentation. All code will be published on GitHub.

Xceptance will continue to maintain and extend XLT as before. Releases will be built and published by Xceptance on a regular schedule. Libraries will be published to Maven Central as part of the open-sourcing process. The latest releases will be available from the XLT GitHub repository as well. Of course, the GitHub defect tracker will start to be your source for feature development and defect fixes.

If you are interested in training, projects, or support for XLT and load testing in general, we of course also offer those services, and will expand this offering further in upcoming months.

By open sourcing, we are opening a new chapter for XLT and we invite everyone to join us. More to come!

Java Training Sessions

Today we are going to publish four of our Java training sessions so you can use the material and benefit from it.

Let’s get started with four direct links to extensive material that might help you to understand Java or code quality better or just help you to reflect on topics you already know.

  • The Java Memory Model: Why you have to know the JMM to understand Java and write stable, correct, and fast code.
  • Java Memory Management: Know more about the size of objects and how Java does garbage collection.
  • High Performance Java: All about the smart Java internals that turn your code into fast code and how you can leverage that knowledge.
  • High Quality Code: The anatomy of high quality code that supports longevity, cross-team usage, and correctness. This is not just about Java, this is about good code in general.

Show a little patience when loading the training, these are all large reveal.js based slide sets. Use the arrow keys or space to navigate. Because the slide sets are designed to be interactive sessions, in many cases, not the entire slide context is revealed at once but block by block.

We publish these training sessions because they are also based on openly shared material, it greatly helped us to advance and understand, as well of course advertise a little what Xceptance might be able to do for you.

We will release more of our material in the next weeks and month, so everybody can browse and learn. This won’t be limited to Java and also cover material about approaching load testing, how to come up with test cases, and more about the modern web and its quality and performance challenges. Of course there will be more Java material too. You can get a glimpse of it when you just follow this link and page through the slides: The Infinite Java Training. Please remember, not all material is complete yet.

If you like the material and you need an audio track aka a real presentation, please talk to us. If you see other training needs in the area of quality assurance, testing, and Java, please contact to us.

More to come.
