A Supervisor Cluster can either use the vSphere networking stack or VMware NSX-T™ Data Center to provide connectivity to Kubernetes control plane VMs, services, and workloads. The networking used for Tanzu Kubernetes clusters provisioned by the Tanzu Kubernetes Grid Service is a combination of the fabric that underlies the vSphere with Tanzu infrastructure and open-source software that provides networking for cluster pods, services, and ingress.
