Cilium (computing)
Cilium is a cloud native technology for networking, observability, and security. It is based on the kernel technology eBPF, originally for better networking performance, and now leverages many additional features for different use cases. The core networking component has evolved from only providing a flat Layer 3 network for containers to including advanced networking features, like BGP and Service mesh, within a Kubernetes cluster, across multiple clusters, and connecting with the world outside Kubernetes. Hubble was created as the network observability component and Tetragon was later added for security observability and runtime enforcement. Cilium runs on Linux and is one of the first eBPF applications being ported to Microsoft Windows through the eBPF on Windows project.
Evolution from Networking CNI (Container Network Interface)
Cilium began as a networking CNI for container workloads. It was originally IPv6 only and supported multiple container orchestrators, like Kubernetes. The original vision for Cilium was to build an intent and identity-based high-performance container networking platform. As the cloud native ecosystem expanded, Cilium added new projects and features to address new problems in the space.
The table below summarises some of the most significant milestones of this evolution:
Cilium was accepted into the Cloud Native Computing Foundation on October 13, 2021 as an incubation-level project. It applied to become a graduated project on October 27, 2022. It became a Graduated project one year later. Cilium is one of the fastest-moving projects in the CNCF ecosystem.
Cilium has been adopted by many large-scale production users, including over 100 that have stated it publicly, for example:
Cilium is the CNI for many cloud providers including Alibaba, APPUiO, Azure, AWS, DigitalOcean, Exoscale, Google Cloud, Hetzner, and Tencent Cloud.
Cilium began as a container networking project. With the growth of Kubernetes and container orchestration, Cilium became a CNI, providing basic things like configuring container network interfaces and Pod to Pod connectivity. From the beginning, Cilium based its networking on eBPF rather than iptables or IPVS, betting that eBPF would become the future of cloud native networking.
