You can enable a Supervisor with vSphere networking or NSX to provision connectivity to Kubernetes control planes, services, and workloads.
A Supervisor that uses the vSphere networking stack is backed by a vSphere Distributed Switch and requires a load balancer to provide connectivity to DevOps users and external services. The NSX Advanced Load Balancer and the HAProxy load balancers are supported for vSphere 7.0 Update 2.
A Supervisor that is configured with NSX, uses the software-based networks of the solution and an NSX Edge load balancer to provide connectivity to external services and DevOps users.
