Building Resilient Microservices with Istio and OpenShift Service Mesh

As microservice architectures grow, managing communication, security, and visibility between services becomes increasingly complex. This text-based course guides you through the foundational concepts of service meshes, showing you how to regain control of your distributed applications. You will transition from basic microservice deployment to orchestrating a highly resilient, secure, and observable application network. Through clear written explanations and practical configuration scenarios, you will learn to manage traffic, enforce security policies, and monitor system health without changing your application code. What you'll learn: Understand service mesh architecture, key terminology, and the role of the data plane and control plane; Configure advanced traffic routing, including canary deployments, blue-green releases, and circuit breakers; Implement zero-trust security with mutual TLS (mTLS) and fine-grained access control policies; Monitor microservice health and performance using modern observability and tracing concepts; Manage service-to-service communication policies within OpenShift Service Mesh; Practice troubleshooting common service mesh configuration issues through structured written scenarios. The course begins with essential definitions of microservices and service meshes before moving step-by-step into traffic management, security configurations, and observability patterns. You will read detailed explanations and analyze real-world configuration files to build a deep, practical understanding. Designed for system administrators, developers, and platform engineers who are new to service meshes, this course requires no prior experience with Istio or OpenShift Service Mesh. Start reading today to build resilient, secure, and easily manageable microservice architectures.
