-### Big Cloud Fabric from Big Switch Networks
-
-[Big Cloud Fabric](https://www.bigswitch.com/container-network-automation) is a cloud native networking architecture, designed to run Kubernetes in private cloud/on-premises environments. Using unified physical & virtual SDN, Big Cloud Fabric tackles inherent container networking problems such as load balancing, visibility, troubleshooting, security policies & container traffic monitoring.
-
-With the help of the Big Cloud Fabric's virtual pod multi-tenant architecture, container orchestration systems such as Kubernetes, RedHat OpenShift, Mesosphere DC/OS & Docker Swarm will be natively integrated alongside with VM orchestration systems such as VMware, OpenStack & Nutanix. Customers will be able to securely inter-connect any number of these clusters and enable inter-tenant communication between them if needed.

-BCF was recognized by Gartner as a visionary in the latest [Magic Quadrant](https://go.bigswitch.com/17GatedDocuments-MagicQuadrantforDataCenterNetworking_Reg.html). One of the BCF Kubernetes on-premises deployments (which includes Kubernetes, DC/OS & VMware running on multiple DCs across different geographic regions) is also referenced [here](https://portworx.com/architects-corner-kubernetes-satya-komala-nio/).

 ### Calico
 
 [Calico](https://docs.projectcalico.org/) is an open source networking and network security solution for containers, virtual machines, and native host-based workloads. Calico supports multiple data planes including: a pure Linux eBPF dataplane, a standard Linux networking dataplane, and a Windows HNS dataplane. Calico provides a full networking stack but can also be used in conjunction with [cloud provider CNIs](https://docs.projectcalico.org/networking/determine-best-networking#calico-compatible-cni-plugins-and-cloud-provider-integrations) to provide network policy enforcement.
