About Cilium

Cilium is a CNCF graduated project that uses eBPF technology to provide high-performance networking, security, and observability for Kubernetes. It replaces kube-proxy and traditional CNI plugins with eBPF programs running in the Linux kernel.

Networking features include pod networking, load balancing, bandwidth management, and multi-cluster connectivity (Cluster Mesh). Service mesh capabilities are provided without sidecars through eBPF.

Cilium Network Policy supports L3/L4 and L7 policies with identity-based security. Hubble provides deep network observability with flow logs, metrics, and a service dependency map.

Cilium has become the default CNI for Google Kubernetes Engine and is widely adopted for its performance advantages over iptables-based networking solutions.
