DO378: Red Hat Cloud-native Microservices Development with Quarkus

Learn to develop microservice-based applications with Quarkus and OpenShift. Many enterprises are looking for a way to take advantage of cloud-native architectures, but many do not know the best approach. Quarkus is an exciting new technology that brings the reliability, familiarity, and maturity of Java Enterprise with a container-ready lightning fast deployment time. This training emphasizes learning architectural principles and implementing microservices based on Quarkus and OpenShift. You will build on application development fundamentals and focus on how to develop, monitor, test, and deploy modern microservices applications..

This course is based on OpenShift 4.5 and Quarkus 1.7


This course is designed for application developers.


Red Hat recommends these prerequisites:

  • Experience with application development or Red Hat Application Development I: Programming in Java EE (AD183)
  • Be proficient in using an IDE such as Red Hat® Developer Studio or VSCode
  • Recommended, but not required: experience with Maven and version control.
  • Recommended, but not required: experience with OpenShift or Introduction to OpenShift Applications (DO101)

Course outcome

As a result of attending this course, you will understand how to develop, monitor, test, and deploy microservice-based applications using Quarkus and Red Hat OpenShift.
You should be able to demonstrate these skills:

  • Design a microservices-based architecture for an enterprise application.
  • Quickly build and test microservices with Quarkus and deploy on to OpenShift Container Platform.
  • Implement fault tolerance and health checks for microservices.
  • Secure microservices to prevent unauthorized access.
