DO378 Red Hat Cloud-native Microservices Development with Quarkus

DO378 Red Hat Cloud-native Microservices Development with Quarkus

Course description

Develop microservice-based applications with Quarkus and OpenShift.

Enterprises are moving to cloud-native microservices architectures. Quarkus is an exciting new technology that brings the reliability, familiarity, and maturity of Java Enterprise with a container-ready lightning fast deployment time. Red Hat Cloud-native Microservices Development with Quarkus (DO378) 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 4.12 and Quarkus 2.13
