Kubernetes Service Mesh with Istio, Kiali, Jaeger, and Cert-Manager

Managing communication between microservices in Kubernetes can quickly become complex, leading to security gaps and visibility blind spots. This text-based course guides you through establishing a robust service mesh to regain control over your containerized applications. You will learn how to secure traffic, trace requests, and automate security certificates using industry-standard open-source tools. By completing this course, you will transform how you manage Kubernetes deployments, moving from basic container orchestration to a highly observable, secure, and resilient microservices architecture. What you'll learn: - Understand the core concepts of a service mesh and why it is essential for modern microservices architectures - Configure Istio to manage, route, and secure traffic between Kubernetes services - Visualize your microservices network and traffic flow in real-time using Kiali - Track and debug distributed requests across services using Jaeger tracing - Automate SSL/TLS certificate generation and renewal within Kubernetes using Cert-Manager - Apply modern zero-trust security patterns to secure service-to-service communication This course begins with foundational definitions and key terminology of service meshes before guiding you through step-by-step configuration scenarios. You will read clear explanations, analyze practical configuration files, and learn to troubleshoot common connectivity and security issues. This course is designed for software developers, system administrators, and DevOps beginners who already understand basic Kubernetes concepts and want to scale their skills to production-grade infrastructure management. No prior service mesh experience is required. Start reading today to build a secure, observable, and resilient Kubernetes infrastructure.
