Quarkus

Writing queryable APIs with MicroProfile GraphQL

“GraphQL is a data query language developed internally by Facebook in 2012 before being publicly released in 2015. It provides an alternative to REST and ad-hoc web service architectures.”

In this talk, we will

Go through the basics of GraphQL
Discuss the differences with REST
Discuss the features in the current and future MicroProfile GraphQL API
Go through a basic example in Java using Quarkus.

We will look at the following GraphQL concepts:

Write tests that spark flow

Sebastian Daschner (IBM)

For most enterprise projects, testing is not really fun. It’s boring, cumbersome, and takes time and effort — especially for distributed applications or when changes in existing functionality forces test scenarios to adapt. Still, software tests are crucial; so, how can we tackle them in an effective and productive way?

Cloud-native Java for this decade with Quarkus

Sebastian Daschner (IBM)

Enterprise Java has come a long way. What does a modern development approach look like, in the age of Jakarta EE and MicroProfile APIs?

In this session, we’ll have a look at supersonic, subatomic Java with Quarkus. If you’re familiar with enterprise development with Spring or Java EE, you’ll be delighted to see the effective way of working, Quarkus enables. We’ll see the benefits of Quarkus for modern, cloud-native microservices in the year 2020. Get yourself ready for this live-coding-only session!

A comparative review of microservice frameworks

Karsten Thoms (itemis AG)

Hendrik Ebbers (Open Elements GmbH)

In this session we will compare some of the most popular Microservice frameworks in the Java ecosystem like SpringBoot, Quarkus, Eclipse MicroProfile, and more. We will give an overview and jumpstart for each framework. Next to this we will answer questions like:

Create Supersonic Subatomic MicroProfile Apps with Quarkus

Dimitris Andreadis (Red Hat)

Java based software development has been a winning proposition for the past 20+ years, however, cloud native application development in the form of microservices and serverless apps are challenging the Java deployment model in terms of memory requirements and start up speed. Quarkus is a Kubernetes native Java stack that can tailor your application for GraalVM & Hotspot providing amazingly fast boot times and incredibly low RSS memory usage, making Java great again in this new Cloud Native Era.

Developer Joy: Quarkus with Eclipse MicroProfile

Daniel Oh (Red Hat)

Eclipse MicroProfile helps developers quickly get started cloud-native app development using Jakarta EE capabilities. But what does this really look like if you're, say, a Java developer? What else the developer joy for Java application? Quarkus not only brings a cohesive, fun to use full-stack framework by leveraging best of breed libraries likeEclipse MicroProfile you love and use wired on a standard backbone but also combining imperative and reactive codes based JVM and/or GraalVM.

Learn to build Cloud Native Java Applications with Quarkus

Kamesh Sampath (Harness)

Alex Soto (Red Hat, Inc.)

Java assumed the whole computer belonged to itself, that it could consume all available memory and CPU. In this presentation, we will demonstrate the problems associated using Java for “microservices”, and how the open source ecosystem is working to insure the future of Java by being cloud first, container native, serverless focused and Kubernetes optimized. This is where GraalVM meets Quarkus (https://quarkus.io), bringing server-side and enterprise-capable Java to enable you to build truly cloud native apps.

Quarkus the shrink ray to your Cloud Native Java Applications

Kamesh Sampath (Harness)

Historically Java was able to handle the biggest enterprise problem(s) with its Write once,run anywhere(WORA) paradigm. With Cloud Native Applications grown to popularity, things like running applications as linux containers, serverless taking centre stage -- Java was pushed back by languages like golang, node.js as the forerunner to build Cloud Native Applications as they are smaller, quicker and arguably more nimble.
