Quarkus Foundation

Trainer(s): Jago de Vreede, duration: 2 days (2x 8 hours)

Introduction by the trainer (in Dutch, in cooperation with our partner Expandior)

In this training you will learn the foundation of building a Quarkus application from scratch and you will gain hands-on experience with best practices and details of this framework. Based on a migration case where you will learn to migrate an existing application to Quarkus.

Detailed description
Quarkus is designed to work with popular Java standards, frameworks, and libraries like Eclipse MicroProfile and Spring as well as Apache Kafka, RESTEasy (JAX-RS), Hibernate ORM (JPA), Spring, Infinispan, Camel, and many more. In this training, you will build a banking application that uses most of the basic frameworks that you will encounter in the real world like RESTEasy, Hibernate and REST clients. When the first day is over you should be able to build a microservice and call that from the main application that also handles the UI and data storage. Of course in all tested with unit test and integration tests.

After you gained the basic knowledge to build Quarkus application in a green field project you will build on that knowledge and use that to migrate a sample JEE application to Quarkus with microservices. The migrated application must comply with the container-first philosophy that means that the application and microservices will run in docker and are compiled to native code to optimize the memory footprint and startup time.

Target audience
This training is suitable for any developer with a Java background who wants to learn the the philiosophy, essentials and best practices of working with Quarkus in various scenarios.
