{ "item_title" : "Modern Software-Defined Networking (SDN)", "item_author" : [" Alira Vexel "], "item_description" : "Software-Defined Networking has moved far beyond academic models and vendor-specific controllers. In 2026, SDN is the operational backbone of modern infrastructure, powering Kubernetes platforms, cloud-native networks, Zero-Trust security architectures, and large-scale automation workflows. Yet many books still focus on theory, outdated protocols, or abstract concepts that fail to translate into real-world operational skill.Modern Software-Defined Networking (SDN): Design, Automate, and Secure Programmable Networks for Cloud, Kubernetes, and Zero-Trust Environments is a purely practical, hands-on guide for engineers who need to build, operate, and secure modern networks using SDN principles that actually work in production.This book takes an operator-first approach. Instead of device-level configuration and static diagrams, you will learn how SDN is implemented using Linux networking, overlays, APIs, declarative policy, GitOps automation, and Zero-Trust enforcement. Every concept is reinforced through structured practice labs, troubleshooting runbooks, and a full-stack capstone project that mirrors real production workflows.You will design SDN architectures by plane, implement programmable data planes using Linux and VXLAN overlays, enforce identity-based Zero-Trust policies, automate network changes safely using Git-driven workflows, and validate behavior through observability and failure testing. The focus throughout is on deterministic outcomes, auditability, and operational discipline-not vendor lock-in or abstract theory.What You Will LearnHow modern SDN actually works in 2026-beyond OpenFlow and legacy modelsDesigning SDN architectures using control, data, policy, and observability planesBuilding SDN fabrics with Linux networking and overlay technologiesImplementing Zero-Trust networking with default-deny, identity-based policiesAutomating SDN changes using GitOps, validation pipelines, and safe rollbackMonitoring, troubleshooting, and operating SDN systems with confidenceDeploying a complete end-to-end SDN stack through a hands-on capstone projectWho This Book Is ForThis book is written for network engineers, platform engineers, DevOps practitioners, SREs, and security teams who want practical, production-ready SDN skills. It is ideal for readers working with Kubernetes, cloud platforms, on-prem environments, or hybrid infrastructures, and for those transitioning from traditional networking to programmable, policy-driven systems.Why This Book Is DifferentPurely hands-on: Every chapter includes practice labs and validation stepsModern and up-to-date: Focused on current Linux, Kubernetes, and SDN toolingVendor-neutral: Principles that apply across platforms and environmentsProduction-oriented: Emphasis on safety, observability, auditability, and rollbackEnd-to-end: A complete SDN system, not isolated examplesBy the end of this book, you will not only understand Software-Defined Networking-you will be able to design, implement, secure, automate, and operate it with confidence in real-world environments.This is not a theoretical introduction to SDN.It is a practical blueprint for building modern, programmable networks that scale safely in production.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/824/860/9798248603985_b.jpg", "price_data" : { "retail_price" : "26.00", "online_price" : "26.00", "our_price" : "26.00", "club_price" : "26.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
