DO378 Red Hat Cloud-Native Microservices Development with Quarkus

DO378 Red Hat Cloud-Native Microservices Development with Quarkus develops practical capability in cloud-native Java microservices with Quarkus, REST APIs, data access, configuration, testing, resilience, observability, containers, and OpenShift deployment.

Learners progress through Quarkus Architecture, Development Mode, Dependency Injection, and REST Services; Data Access, Transactions, Validation, Security, and External Services; Testing, Resilience, Messaging, Observability, and Performance; Container Images, OpenShift Deployment, Configuration, Scaling, and Delivery. Each stage connects Red Hat technology with implementation decisions, operational controls, troubleshooting, and reviewable evidence.

The learning journey follows a Java development team modernizing a monolithic service into observable, resilient Quarkus microservices and produces a practical Quarkus microservice repository, API and data design, test evidence, and OpenShift deployment portfolio for implementation and operational use.

What You Will Learn

• Execute Quarkus project architecture and rapid development workflow and interpret outputs, events, logs, and system behavior.
• Diagnose RESTful microservice design and dependency injection through targeted checks, traces, and corrective testing.
• Validate transactional data access and validation against security, reliability, governance, and acceptance criteria.
• Compare secure integration with external services alternatives and explain operational and technical trade-offs.
• Document automated testing and fault-tolerance patterns using repeatable commands, evidence, ownership, and handover notes.
• Improve messaging, metrics, tracing, and health observability through monitoring, exception handling, automation, and review cycles.
• Map container image creation and OpenShift deployment across architecture, roles, dependencies, controls, and evidence.
• Configure cloud-native scaling, troubleshooting, and delivery validation with reproducible settings and validated prerequisites.
