Quarkus Sessions

Optimizing Java on the EU processor platform
Speaker: Christos Kotselidis
Time/Date: Friday, June 16 • 11:15am - 11:50am
Abstract: Both the European Union (EU) and the United States (US) recently started investing in chip design and manufacturing via their respective CHIPS Acts, with the end goal being sovereignty in the semiconductor industry. Part of the EU investments is the recently funded Horizon Europe AERO project. AERO has the single goal of upbringing the necessary software components for cloud-ready deployments over the EU processor designs created by the European Processor Initiative (EPI). In this talk we will provide an overview of the AERO project and will demonstrate two key components of the software stack regarding the Java ecosystem:

1. Quarkus from Red Hat; a Kubernetes Native Java stack tailored for OpenJDK HotSpot and GraalVM's native-image.
2. TornadoVM from the University of Manchester; a JVM plugin for accelerating Java programs on GPUs and FPGAs.

Quarkus Super-Heroes Workshop
Speaker: Martin Štefanko
Time/Date: Saturday, June 17 • 10:15am - 11:35am
Abstract: This workshop offers attendees an intro-level, hands-on session with Quarkus, from the first line of code to making services, to consuming them, and finally to assembling everything in a consistent system. But, what are we going to build? Well, it’s going to be a set of microservices:

• Using Quarkus
• Using HTTP and events (with Apache Kafka)
• With some parts of the dark side of microservices (resilience, health, monitoring with Prometheus)
• Answer the ultimate question: are super-heroes stronger than super-villains?

You are going to learn:

• What is Quarkus, and how you can use it
• HTTP endpoints (REST API) with Quarkus
• Relational database
• Swagger and OpenAPI
• Testing your microservice
• Reactive microservices, including reactive data access
• How to improve the resilience of your service
• Event-driven microservices with Kafka
• Building native executable
• Extending Quarkus with extensions
• And much more!

The whole workshop is available online so you can finish it later if needed.

A day in life of a Quarkus developer
Speaker: Martin Štefanko
Time/Date: Saturday, June 17 • 1:15pm - 1:50pm
Abstract: If you know Quarkus, you heard about the developer joy that is integral for Quarkus to provide. But what is it really? How does it help you with your day-to-day tasks? What benefits or shortcuts does it bring to your work? In this talk, we answer these questions. In this live-coded session, we create a new Quarkus project and show you how to jump-start your Java microservices with many different features that Quarkus brings out of the box. We make it interactive, so if there is something that you want to see, we demonstrate it. But in general, we aim to show typical user application development with a database, remote connections, and security. Of course, we can't leave out packaging into containers and their deployment to OpenShift. Quarkus is a framework that makes the developer productivity (and the mentioned joy that comes with it) a requirement. You will see what we can create with Quarkus in the provided time. And then you will understand what the Quarkus development joy is.
