Calico for Kubernetes

Calico enables networking and network policy in Kubernetes clusters across the cloud. Calico works everywhere - on all major public cloud providers and private cloud as well.

Calico uses a pure IP networking fabric to provide high performance networking, and its battle-tested policy engine enforces high-level, intent-focused network policy. Together, Calico and Kubernetes provide a secure, cloud-native platform that can scale your infrastructure to hundreds of thousands of workloads.
