Develop microservice-based applications in Java EE with MicroProfile and OpenShift
Building on Red Hat Application Development I: Programming in Java EE (AD183), the introductory course for Java EE application development, Red Hat Application Development: Building Microservices with Quarkus (DO283) emphasizes learning architectural principles and implementing microservices in Java EE, primarily based on MicroProfile with WildFly Swarm and OpenShift.
This course is based on Red Hat® Enterprise Application Platform 7.4 and Wildfly Swarm 2018.3.3.
You will build on Java EE application development fundamentals and focus on how to develop, monitor, test, and deploy modern microservices applications. Many enterprises are looking for a way to take advantage of cloud-native architectures, but many do not know the best way to go about it. These enterprises have monolithic applications written in Java Enterprise Edition (JEE).

Learning Objectives

Impact on the organization
Many organizations are struggling with how to make the move from monolithic applications to applications based on microservices, as well as how to reorganize their development paradigm to reap the benefits of microservice development in a DevOps economy. In particular, many organizations are invested in Java programming frameworks and Red Hat® OpenShift Container Platform. This course exposes you to the Wildfly Swarm runtime for streamlined deployment on OpenShift clusters.
Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.
Impact on the individual
As a result of attending this course, you will understand how to develop, monitor, test, and deploy microservice-based Java EE applications using Wildfly Swarm and Red Hat OpenShift.
You should be able to demonstrate these skills:
  • Design a microservices-based architecture for an enterprise application.
  • Implement fault tolerance and health checks for microservices.
  • Secure microservices to prevent unauthorized access.
  • Recommended next exam or course
  • Red Hat Certified Enterprise Microservices Developer Exam (EX283)
  • Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180)
  • Highly recommended for those who don’t have OpenShift experience
  • Red Hat OpenShift Development I: Containerizing Applications (DO288)


  •   Attend Red Hat Application Development I: Programming in Java EE (JB183) or demonstrate equivalent experience
  •   Be proficient in using an integrated development environment such as Red Hat® Developer Studio or Eclipse
  •   Experience with Maven is recommended, but not required
