Istio Service Mesh: Connecting and Securing Microservices

As applications transition to microservices, managing network traffic, security, and observability across dozens of services becomes increasingly complex. This text-based course guides you through the fundamentals of service meshes, showing you how to regain control of your microservices infrastructure. By reading through clear explanations and studying real-world configuration examples, you will learn how to deploy Istio, manage traffic routing, and secure communication without changing a single line of your application code. What you'll learn: - Understand the core concepts of service meshes and how Istio manages microservice communication. - Configure intelligent traffic routing, load balancing, and canary deployments using declarative configuration. - Secure service-to-service communication using mutual TLS (mTLS) and fine-grained authorization policies. - Monitor microservices health and performance through distributed tracing and telemetry concepts. - Explore modern Istio patterns, including sidecar deployments and the fundamentals of sidecarless ambient mesh architecture. You will start with foundational service mesh definitions and architecture before moving on to practical configuration examples for traffic management, security enforcement, and observability. This course is designed for software developers, system administrators, and DevOps beginners who want to understand service mesh architecture with no prior Istio experience required.
