Cilium Kubernetes CNI Provider, Part 1: Overview of eBPF and Cilium and the Installation Process

In this multi-part series, we will take a look at Cilium. In part 1, we will learn what Cilium is and how it leverages a key technology called “eBPF” to provide load balancing, observability, and security. We will also take a look at what eBPF is and conceptually walk through how a simple eBPF program can be organized and loaded into Kernel. We will wrap this episode up by going through a complete walk-through on how to install Cilium and its components on a brand new Kubernetes cluster.
