Building, purpose, aesthetics

Welcome to the first part in the mini-series on software architecture. We start by examining the original source of the term – since the word architecture presumably conjures in most people thoughts of buildings.

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.

Die Anatomie eines erfolgreichen Teams

Die Gründe für das Scheitern von Softwareentwicklungsprojekten sind vielfältig und zum Großteil nicht technischer, sondern organisatorischer Art: Zu hohe Komplexität, unklare Anforderungen, nicht-funktionale Teams, Fokus auf den falschen Dingen oder überhandnehmende Konzernpolitik. Bereits zum Projektstart können Maßnahmen getroffen werden, um einige dieser Risiken einzudämmen und die Aussicht auf einen Projekterfolg zu erhöhen. Dieser Artikel wird den Fokus auf ein funktionierendes, erfolgreiches Entwicklungsteam legen und erörtern, welche Stellschrauben Sie drehen können – und von welchen Sie lieber die Finger lassen sollten.

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.

Testing in Spring Boot applications

In addition to production code, we typically also write tests to discover and correct possible errors as early as possible in the development process. For new functionality, it isn’t even uncommon to write more test code than production code. At the same time, the tests should be as fast as possible, so they can be executed frequently without causing long delays. In this article, we explore how this can be done in applications based on Spring Boot.

No future-proof architectures!

Architecture: The term itself radiates stability. It seems clear, then, that good architecture should be future-proof. But precisely this goal often leads to problems. Does that mean it is better not to design future-proof architectures?

Is Platform Engineering the new DevOps?

When companies transition to the cloud, they anticipate an improved developer workflow, shorter release cycles, and more robust end-to-end team responsibility. However, even after the admin team delivers the new platform with all its capabilities, software teams may hesitate to adopt it and assume responsibility. But why? Is it not every developer’s desire to control the process from committing code to deploying it to production? One possible explanation is a lack of emphasis on the developer experience during platform conceptualization. This article aims to identify common issues and explore whether platform engineering can help to address them.
