DO328 Building Resilient Microservices with Istio and Red Hat OpenShift Service Mesh

DO328 Building Resilient Microservices with Istio and Red Hat OpenShift Service Mesh develops practical capability in Istio and OpenShift Service Mesh architecture, sidecars, traffic management, retries, timeouts, circuit breaking, security, observability, fault injection, gateways, policies, and resilient delivery.

The course progresses through Service Mesh Architecture, Istio Components, Sidecars, Data Plane, and Control Plane; Traffic Management, Routing, Gateways, Retries, Timeouts, and Circuit Breaking; mTLS, Authorization, Policies, Telemetry, Tracing, Metrics, and Logs; Fault Injection, Resilience Testing, Troubleshooting, Rollout, and Operations. Each lesson connects Red Hat technology with implementation choices, security, validation, troubleshooting, and support responsibilities.

Learners work through a platform and development team improving reliability and visibility for distributed microservices and produce a practical service mesh configuration, traffic policy tests, observability evidence, and resilience runbook that can support implementation, review, and operational handover.

What You Will Learn
