Kube-router

Kube-router option is a purpose-built networking solution that aims to provide high performance that's easy to use. It's based on the Linux LVS/IPVS kernel load balancing technologies as proxy. It also uses kernel-based networking and uses iptables as a network policy enforcer. Since it doesn't use an overlay technology, it's potentially a high-performance option for the future.
