Cilium

What is Cilium?

Cilium (cilium.io) is an open source project to provide networking, security, and observability for cloud native environments such as Kubernetes clusters and other container orchestration platforms.

At the foundation of Cilium is a new Linux kernel technology called eBPF (ebpf.io), which enables the dynamic insertion of powerful security, visibility, and networking control logic into the Linux kernel. eBPF is used to provide high-performance networking, multi-cluster and multi-cloud capabilities, advanced load balancing, transparent encryption, extensive network security capabilities, transparent observability, and much more.
