About
Calico is a widely adopted, battle-tested open source networking and network security solution for Kubernetes, virtual machines, and bare-metal workloads. Calico provides two major services for Cloud Native applications:
- Network connectivity between workloads.
- Network security policy enforcement between workloads.
Calico’s flexible architecture supports a wide range of deployment options, using modular components and technologies, including:
- Choice of data plane technology, whether it be eBPF, standard Linux, Windows HNS or VPP
- Enforcement of the full set of Kubernetes network policy features, plus for those needing a richer set of policy features, Calico network policies.
- An optimized Kubernetes Service implementation using eBPF.
- Kubernetes apiserver integration, for managing Calico configuration and Calico network policies.
- Both non-overlay and overlay (via IPIP or VXLAN) networking options in either public cloud or on-prem deployments.
- CNI plugins for Kubernetes to provide highly efficient pod networking and IP Address Management (IPAM).
- A Neutron ML2 plugin to provide VM networking for OpenStack.
- A BGP routing stack that can advertise routes for workload and service IP addresses to physical network infrastructure.
