Cilium: Architecture, Networking, and Security in Kubernetes

"Cilium: Architecture, Networking, and Security in Kubernetes"
"Cilium: Architecture, Networking, and Security in Kubernetes" is a comprehensive and authoritative guide to modern cloud-native networking. Bridging the gap between foundational eBPF concepts and production-grade Kubernetes deployments, this book demystifies the architecture, operational models, and security frameworks that make Cilium the premier choice for scalable, secure, and observable networking in dynamic container environments. Readers will find an in-depth exploration of Cilium’s agent, operator, and Hubble architecture, alongside robust comparative insights with traditional CNI plugins, all rooted in real-world deployment paradigms for clusters of any scale.
At its core, the book systematically unpacks Cilium’s innovative network policy model, advanced pod connectivity, and high-performance load balancing, revealing how eBPF powers next-generation data paths, service discovery, and kube-proxy replacement. A dedicated focus on observability with Hubble, integration with industry-standard monitoring tools, and approaches for long-term analytics provides practitioners with actionable guidance for maintaining robust visibility and control. Security professionals will appreciate in-depth sections on L3/L7 network policies, runtime threat detection, regulatory compliance, and practical incident response tailored to modern Kubernetes clusters.
This essential resource serves architects, platform engineers, and security teams alike, detailing best practices for scalability, reliability, and seamless integration with service meshes, multi-cloud environments, and managed Kubernetes platforms. With prescriptive troubleshooting frameworks, advanced eBPF customization guidance, and forward-looking insights on the evolving Kubernetes networking landscape, "Cilium: Architecture, Networking, and Security in Kubernetes" empowers readers to design, secure, and operate resilient cloud-native networks with confidence.
