Cilium Insights

What is Cilium?

Cilium is an open-source, cloud-native networking and security solution built on top of eBPF (Extended Berkeley Packet Filter). It provides advanced networking, security, and observability features for containerized applications, typically used in Kubernetes environments. Cilium enables features such as network policy enforcement based on service identities, load balancing, service mesh capabilities, and network observability through its eBPF-based architecture.
