Course Overview
Building on Red Hat Application Development I: Programming in Java EE (JB183), the introductory course for Java EE application development, Red Hat Application Development II: Implementing Microservice Architectures (JB283) emphasizes learning architectural principles and implementing microservices in Java EE, primarily based on MicroProfile with WildFly Swarm and OpenShift.
Who should attend
This course is designed for Java developers.
Prerequisites
- 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
Course 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.
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.
