The article discusses the challenges of networking, observability, and security in Kubernetes and container networks, emphasizing the overhead of traditional virtual networking. It highlights the promise of eBPF, a technology that runs custom code in the Linux kernel, to enhance efficiency, visibility, and control in container networking. While containers function as isolated environments, they depend on robust networking for connectivity. The article discusses how existing networking stacks, which rely heavily on iptables and sidecar proxies, become inefficient at scale, paving the way for eBPF as a solution for modern software networking needs.
"In the world of distributed computing, everything goes over the network, making it the critical component for applications to work and work together," says Bill Mulligan.
"Traditional container networking stacks primarily relied on iptables and sidecar proxies to manage network traffic," says Taranvir Singh.
