"Istio in Depth"
"Istio in Depth" is an authoritative guide that unpacks the complexities of service mesh technology with a comprehensive focus on Istio, the industry-leading open-source solution for securing, managing, and observing microservices. The book systematically explores Istio's architectural foundations, starting with the history and evolution of service meshes, a detailed breakdown of core components, and best practices for scalability, reliability, and extensibility. It provides hands-on insights into deploying Istio in both single- and multi-cluster environments, highlighting the strategic goals that drive modern cloud-native systems.
Diving into practical integration, this book offers a deep-dive into operationalizing Istio on Kubernetes, including custom resource definitions, automatic and manual sidecar injection, and strategies for multi-tenancy, upgrades, and legacy workload integration. Readers are guided through the core pillars of traffic management, security, and observability—mastering advanced routing, policy control, zero-trust security architecture, and full-stack telemetry with tools like Prometheus, Grafana, and Jaeger. Cutting-edge chapters illustrate how to extend Istio with WebAssembly plugins, integrate with external policy engines, and engineer dynamic mesh topologies for hybrid and federated cloud environments.
"Istio in Depth" is also a practical operations handbook, addressing production-scale installation, lifecycle automation, troubleshooting, disaster recovery, and cost optimization. Real-world adoption stories, current advancements, and future roadmaps place Istio in a broader cloud-native ecosystem, equipping architects, platform engineers, and DevOps practitioners with the knowledge and confidence to lead secure, resilient, and observable microservice infrastructures. This book is an indispensable resource for anyone looking to master service mesh technologies and drive innovation in distributed systems.
