Building Resilient Microservices with Istio and OpenShift Service Mesh

As microservice architectures grow, managing communication, security, and observability between services becomes increasingly complex. This text-based course guides you through the foundational concepts of service meshes, showing you how to tame distributed systems without altering your application code. You will transition from basic microservice deployments to designing resilient, self-healing service networks. Through structured written explanations and practical configuration scenarios, you will learn to manage traffic, enforce security policies, and monitor system health using Istio and OpenShift Service Mesh. What you'll learn: - Understand the core architecture of service meshes, including control plane and data plane dynamics. - Configure advanced traffic routing, canary deployments, and blue-green releases. - Implement zero-trust security using mutual TLS (mTLS) and fine-grained access controls. - Apply resilience patterns like circuit breakers, retries, and rate limiting to prevent cascading failures. - Monitor microservice health with distributed tracing and telemetry integration concepts. - Prepare for professional service mesh exams by mastering core configuration patterns. The course begins with essential service mesh terminology and architecture before moving into hands-on configuration files, traffic management strategies, and security policies. You will progress systematically from basic concepts to advanced resilience patterns. This course is designed for system administrators, developers, and cloud engineers who are new to service meshes. No prior experience with Istio or OpenShift Service Mesh is required, though a basic understanding of container concepts is helpful.
