Cilium
Cilium is a network, observability and security solution based on the eBPF data plane. By dynamically running the eBPF byte code in the Linux kernel, L3-L7 implements network policies in layers and can replace the kube-proxy component. It offers features such as multi-cluster support, distributed load balancing, and integrated gateways.
