Episode: Cilium: Programmable Linux Networking with Dan Wendlant and Thomas Graf
Description: Cilium is open-source software built to provide improved networking and security controls for Linux systems operating in containerized environments along with technologies like Kubernetes. In a containerized environment, traditional Layer 3 and Layer 4 networking and security controls based on IP addresses and ports, like firewalls, can be difficult to operate at scale because of the volatility of the system. Cilium is eBPF, which is an in-kernel virtual machine which attaches applications directly to code paths in the kernel. In effect, this makes the Linux kernel “programmable” without changing kernel source code or loading modules. Cilium takes advantage of this functionality to in...
