Quarkus Foundation

Trainer(s): Alexei Bratuhin, duration: 2 days (2x 8 hours)

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

Introduction
In this comprehensive training you will master the foundations of building enterprise-grade Quarkus applications from scratch, gaining hands-on experience with cutting-edge features and best practices. You’ll explore Quarkus’ latest innovations including Continuous Testing for immediate feedback, Dev Services for zero-configuration development environments, and cloud deployment patterns optimized for modern container platforms. Based on real-world migration scenarios, you’ll learn to transform existing applications into cloud-native Quarkus solutions.

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 comprehensive banking application leveraging the frameworks you’ll encounter in enterprise development like RESTEasy, Hibernate and REST clients. You’ll experience Quarkus’ revolutionary developer productivity features including live reload, Dev Services that automatically provision databases and messaging infrastructure, and Continuous Testing that provides instant feedback as you develop. When the first day concludes, you’ll confidently build microservices with modern testing strategies and integration patterns.

On the second day, you’ll apply your foundation knowledge to migrate a sample JEE application to Quarkus with microservices architecture. The migrated application will embrace the container-first philosophy, running efficiently in Docker containers with options for native compilation to dramatically optimize memory footprint and startup time. You’ll also explore advanced cloud deployment patterns including Kubernetes-native features and modern observability practices.

Target audience
This training is suitable for Java developers who want to master the philosophy, advanced features, and enterprise best practices of Quarkus across various development and deployment scenarios, including cloud-native environments.
