DO283 Red Hat Application Development II: Implementing Microservice Architectures

DO283 Red Hat Application Development II: Implementing Microservice Architectures

Course description

Develop microservice-based applications in Java EE with MicroProfile and OpenShift

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 (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).

Course summary

  • Deploy and monitor microservice-based applications.
  • Implement a microservice with MicroProfile.
  • Implement unit and integration tests for microservices.
  • Use the config specification to inject data into a microservice.
  • Create a health check for a microservice.
  • Implement fault tolerance in a microservice.
  • Secure a microservice using the JSON Web Token (JWT) specification.

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.
