Quarkus for Java Native and Microservice Development

• An understanding of Java programming
• Experience with web architecture and REST concepts
• Familiarity with the HTTP protocol

Audience

• Developers
• Software architects
• Engineers building cloud-native applications

Quarkus is a high-performance Java framework designed for building cloud-native, container-first, and serverless applications.

This instructor-led, live training (online or onsite) is aimed at intermediate-level to advanced-level developers and architects who wish to develop Java native applications and microservices using Quarkus with optimized memory usage and startup time.

By the end of this training, participants will be able to:

• Develop high-performance, lightweight Java native applications using Quarkus.
• Build and deploy RESTful services and microservices architectures.
• Use GraalVM for native compilation and optimize startup and memory efficiency.
• Package and containerize applications for Kubernetes and OpenShift environments.

Format of the Course

• Interactive lecture and discussion.
• Lots of exercises and practice.
• Hands-on implementation in a live-lab environment.
