Buzzing Beyond Clouds picks up where Buzzing Across Space left off, after Obee showed us how eBPF makes the Linux kernel programmable. In Buzzing Beyond Clouds, Obee puts those eBPF-powered skills to work connecting planets, building observability systems, and defending communities, in a galaxy spanning adventure that maps to what Cilium actually does: CNI, Cluster Mesh, Hubble, network policy, service mesh, and runtime security with Tetragon. This book will help you: Understand what Cilium is and why it is the CNI powering some of the world's largest Kubernetes clusters. Get an overview of Cilium's core capabilities from networking and network policy to observability with Hubble and runtime security with Tetragon. Explain and illustrate Cilium in a way everyone can understand.
