Cilium is now considered the de facto cloud native networking platform for Kubernetes, connecting, securing, and monitoring millions of applications across thousands of clusters. With such versatility and feature-richness, Cilium can be daunting to learn. This comprehensive guide breaks Cilium down, making it broadly accessible to the increasing number of users who'll encounter the platform in their careers.Nico Vibert, Filip Nikolic, and James Laverack, all from Isovalent (creators of eBPF and Cilium), take you through how Cilium works, the problems it can solve, and how to run it in production. If you're an experienced platform engineer or network architect who wants to get on top of the next big thing in cloud networking, this book is for you.Learn about Kubernetes networking and the role of CiliumDive into the various use cases Cilium addressesUnderstand Cilium's architecture and how it moves packets aroundSecure workloads through the use of network policiesConnect multiple clusters for service load balancing and discoveryObserve application networking performance for troubleshooting and forensicsLeverage Cilium's built-in service mesh and networking capabilities for complex traffic engineering
