Technologies for the Integration of Services

In the course of an internal study, we asked a number of INNOQ consultants about their experiences in current or past development projects. One interesting topic here was the integration of microservices and self-contained systems (SCS). Asynchronous communication is frequently used in distributed systems to enable better scalability, greater resilience, and looser coupling. In this article, you will read what insights we learned in our conversations.

Zukünftige Features des JDK

Ich weiß nicht, wie es Ihnen geht, aber seitdem mit JDK 9 der Release-Zyklus des JDK auf sechs Monate verkürzt wurde und wir mittlerweile, dank Preview und Incubator, auch Features bereits vor der vollständigen Fertigstellung ausprobieren können, wirkt das JDK lebendiger als eh und je. In diesem Artikel wollen wir deswegen einen Blick in die Zukunft werfen und uns aktuelle Preview-Features anschauen, die es vermutlich in naher Zukunft final ins JDK schaffen werden.

The Evolutionist

The current training and further education of software developers strongly focuses on the development of new software. Conferences and trade magazines are full of new programming languages, new tools, new hypes, which seemingly never cease to amaze. Quick results, direct feedback, and unprecedented productivity are suggested. The urge to incorporate the new into one’s software is awakened – until one is brought back to reality: their own legacy system.

Lokale LLMs mit Ollama und Spring AI nutzen

Egal, ob wir wollen oder nicht, um AI und speziell Large Language Models (LLM) kommen wir aktuell nicht herum. Mich schrecken solche Hypes zwar aus Reflex eher ab. Allerdings sieht es so aus, als würde von diesem Hype mehr bleiben als vom letzten, der Blockchain. Deshalb wollen wir uns in diesem Post einmal anschauen, wie man ein LLM lokal aufsetzen kann und dieses mittels Spring AI in eine Spring Boot-Anwendung einbinden kann.

Automatisierte Code-Wartung mit OpenRewrite

In Teil 1 dieser Serie habe ich gezeigt, wie OpenRewrite im Rahmen von Softwareentwicklungsprojekten zur Automatisierung von Code-Wartungsaufgaben verwendet werden kann. In diesem Beitrag zeige ich nun, wie man eigene OpenRewrite-Rezepte schreibt. Das hilft Dir nicht nur dabei, Refactoring-Aufgaben auszuführen, für die es keine öffentlich zugänglichen Rezepte gibt, sondern auch dabei, zu verstehen, wie OpenRewrite unter der Haube funktioniert.

Automated code maintenance with OpenRewrite

With the large number of software development projects in most organisations, keeping these projects up to date with the latest security patches and framework updates can be quite a task. OpenRewrite is a library that provides an automated solution to this problem. Using recipes written in Java, it can perform large-scale source code refactoring during the build process, preserving as much of the original code as possible. In this blog post, I will explain how OpenRewrite works and how you can use it to refactor your code base.

Testing your GitLab CI/CD pipeline

If you develop a pipeline as a service for other development teams you should treat it as a product and establish product development processes, a versioning strategy, etc. around it. Besides that, as potentially many teams will use and rely on your pipeline you want to make sure that new features don’t break existing functionality. This ensures that your customer base remains happy and able to deliver business value. Therefore you need some sort of testing and we will demonstrate a way to (integration-) test your GitLab CI/CD pipeline.

JDK 21, the next long-term support release

The newest JDK release, version 21, appeared on September 19th. A number of developers view it as a long-term support release that will be supported for at least the next five years. As many applications will presumably be updated to version 21 from JDK 17, the last long-term support release, we would like to take this opportunity to examine the relevant changes from 17 to 21.
