Abstracts

Increasing Portability in a Containerized World (Spoiler: It’s More Than Just Docker)—Jeffrey Janssen (SVB)

When we talk about portability, containers often steal the spotlight. But what happens when you’re migrating an entire DevOps process—from on-prem OpenShift on bare metal and CI/CD pipelines to the cloud? It’s not just about containers: it's about transforming the way your Java applications are built, deployed, and scaled in a cloud-native world.

In this session, I’ll take you through our journey of moving everything to the cloud: setting up cloud-based CI/CD pipelines, using OpenShift in Azure, and automating everything with ArgoCD based on GitOps principles. This talk focuses on the DevOps techniques surrounding Java applications—how to make them portable, how to integrate them into cloud environments, and how to automate the deployment process for faster, more scalable solutions.

If you're a Java developer looking to understand how cloud-native DevOps practices can help automate your workflows and scale your applications, this session is for you.

Level Up Your Java Streams with Gatherers—Hinse ter Schuur (SDB Professionals)

Since Java 8, the Stream API has been a valuable tool for Java developers. However, our hunt for better solutions has often left us wanting more. Until now, we could only use the standard provided intermediate operations on streams, like map, filter, and flatMap.

Enter Java 24's new Stream Gatherers, which allow for adding custom intermediate operations to our streams.

In this session, you'll learn what Gatherers are, where they shine, and how you can implement your own. By the end of the session, you'll be fully equipped to use this powerful new feature in your day-to-day work.

Be More Productive with IntelliJ IDEA—Marit van Dijk (JetBrains)

IntelliJ IDEA is designed to help developers stay in the flow while working. It has a powerful editor, refactorings, navigation, and all kinds of smart features to help you write and read code. At the same time, it is jam packed with tools professional developers need, like Maven, Gradle, Spring, Git, Databases, Test tools and more. And did I mention a fantastic debugger?

In this talk, you will see how IntelliJ IDEA supports your workflow without having to leave the IDE, and learn how you can be a happier and more productive developer.
