Resilient Microservices with OpenShift Service Mesh: Exam Study Guide

Modern cloud-native architectures rely on microservices, but managing communication, security, and observability across dozens of services can be incredibly complex. This written course provides a clear, step-by-step pathway to mastering service mesh technology on OpenShift and preparing for specialist certification. You will transition from understanding basic container communication to configuring advanced traffic routing, zero-trust security, and deep telemetry, gaining the practical knowledge required to build highly resilient microservices architectures. What you'll learn: - Understand the fundamental architecture of OpenShift Service Mesh and control planes. - Configure advanced traffic management, including canary deployments, ingress routing, and load balancing. - Apply zero-trust security principles using mutual TLS (mTLS) and fine-grained authorization policies. - Monitor microservice health and performance using modern observability tools like Kiali, Prometheus, and Jaeger. - Implement resilience patterns such as circuit breakers, retries, and rate limiting to prevent cascading failures. - Practice troubleshooting common service mesh configuration issues through guided written scenarios. The course begins with foundational concepts of microservices and service mesh architecture before progressing to configuration patterns for traffic, security, and monitoring. Every module is designed to reinforce the core competencies tested in professional microservices examinations. This course is designed for developers, DevOps engineers, and system administrators who are new to service meshes or preparing for specialist exams. No prior service mesh experience is required, though a basic familiarity with containers and Kubernetes concepts is helpful.
