Quarkus

DevNation Tech Talk: Building portable cloud applications with Quarkus, Azure Radius, Skupper, and Backstage

Learn how to use an external database with Quarkus and link an example application to an external Microsoft SQL Server database in this tutorial.

Learn how to create a Java application that uses AI and large-language models (LLMs) by integrating the LangChain4j library and Red Hat build of Quarkus.

Discover how to integrate cutting-edge OpenShift AI capabilities into your Java applications using the OpenShift AI integration with Quarkus.

This talk introduces the basic principles of optimization and pitfalls to avoid. We’ll dive into why the exact same techniques that make Quarkus rocket-fast were considered a terrible idea fifteen years ago; why fast benchmarks make for slow programs; why Project Loom may not be the speedup you’re hoping for; and why—even though it can be easy to get wrong—optimization really, really matters.

Discover how application class data sharing (AppCDS) can help reduce startup time of your OpenJDK apps.

This article discusses how to upgrade the QOSDK and Quarkus code so that future installments can be done with recent versions of the projects.

Get an introduction to Quarkus extensions and find out why they are an integral part of the Quarkus ecosystem.

Applications today don't exist in a vacuum; they typically communicate with other services, such as databases, message brokers, cache servers, and more. These interconnectivity requirements make it hard to do local/inner-loop development and testing efficiently, often forcing developers to write lots of code and configuration that never gets to production. What if there was a better way?

What if you didn’t need to write any extra code or configuration, and things just worked out of the box, making your life simpler and easier?
