Cilium Network

Cilium v1.19.4 — eBPF-based CNI, networking, and security for Kubernetes.

Overview

Cilium provides pod networking via eBPF, replacing kube-proxy with socket-level load balancing. Security policies enforce L3-L7 rules based on identity (not IP), surviving pod churn. Hubble delivers observability. LB IPAM + L2/BGP announcements expose Services externally without a cloud LB.
