{ "item_title" : "Istio for Modern Infrastructure", "item_author" : [" Michael Nicholas "], "item_description" : "Build a More Secure, Resilient, and Manageable Kubernetes Service MeshModern microservices need more than reliable application code. They need secure communication, predictable traffic management, useful telemetry, and a consistent way to handle failures across distributed services. As Kubernetes environments grow, managing these responsibilities individually becomes harder-and small configuration mistakes can quickly turn into production incidents.Istio for Modern Infrastructure: Building Secure Service Meshes, Managing Traffic, and Operating Cloud-Native Applications at Scale is a practical guide to using Istio to solve these challenges in real-world environments.Rather than treating a service mesh as something to install and forget, this book explores how to introduce Istio into an existing Kubernetes platform, apply its capabilities safely, and operate it as part of a sustainable infrastructure strategy.Inside this book, you will learn how to: Introduce Istio into Kubernetes with a controlled rollout approach that accounts for existing workloads, configuration, and operational risk.Manage service traffic safely using routing strategies that support deployments, API changes, and controlled traffic shifts.Configure retries and timeouts without creating retry storms, increasing queue pressure, or making dependency failures worse.Secure service-to-service communication with workload identity, mutual TLS, and appropriate access controls.Control ingress, egress, and external dependencies while maintaining clear boundaries around communication with services outside the mesh.Use mesh telemetry during incidents to investigate latency, traffic behavior, and communication failures more effectively.Troubleshoot Istio misconfigurations by connecting configuration problems to observable symptoms and practical diagnostic steps.Scale Istio responsibly without multiplying operational complexity or introducing unnecessary platform overhead.Avoid production mistakes that turn routine changes into outages.Develop a long-term operating model built around clear ownership, repeatable validation, safe upgrades, and ongoing platform improvement.Practical Guidance for Real Production EnvironmentsThroughout the book, practical configurations and production-oriented scenarios demonstrate how Istio fits into the wider Kubernetes environment. An evolving e-commerce platform provides a consistent example of how traffic management, service security, observability, and operational decisions interact across multiple services.You will also examine an important distinction: configuring a mesh feature is not the same as making an application reliable. Effective results depend on understanding application behavior, selecting appropriate policies, validating changes, and monitoring what actually happens after deployment.Who Should Read This Book?This book is designed for platform engineers, DevOps engineers, site reliability engineers, Kubernetes administrators, and software engineers responsible for cloud-native applications. Familiarity with Kubernetes, containers, networking fundamentals, and distributed services will help you get the most from the examples.Whether you are evaluating Istio for an existing platform or improving a mesh already running in production, this guide will help you make informed engineering decisions, reduce avoidable operational risks, and build a more consistent approach to service communication.Move beyond installing Istio. Learn how to operate it with confidence, control, and a clear understanding of production trade-offs.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/816/529/9798165296642_b.jpg", "price_data" : { "retail_price" : "39.99", "online_price" : "39.99", "our_price" : "39.99", "club_price" : "39.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
