Making the Kubernetes Service Abstraction Scale Using EBPF

Making the Kubernetes Service Abstraction Scale Using EBPF

Explore a scalable reimplementation of the Kubernetes service abstraction using eBPF in this 43-minute Linux Plumbers Conference talk. Delve into recent kernel changes that enabled this implementation and future modifications that could simplify it further. Learn about Kubernetes' architecture, the limitations of the default kube-proxy implementation, and how Cilium leverages eBPF technology to overcome scalability and reliability issues in large-scale Kubernetes deployments. Gain insights into container networking with eBPF, focusing on load balancing and NAT, without requiring prior Kubernetes knowledge.
