To facilitate the communication between vCenter Server instances and hosts from VMware Cloud Provider Program to the on-premises network, the VMware Cloud Provider and customer must determine the means by which communication will be realized.

Where applicable, VMware recommends that WAN connectivity be implemented between the customer and VMware Cloud Provider. This enables more flexibility with onboarding options that require direct connectivity for hosts between sites (for example, long-distance vSphere vMotion migration and VMware vSphere Replication™).

For situations in which WAN connectivity cannot be established, the use of public IP addresses at each site is required with NAT services configured for the NSX Edge and standalone NSX Edge.

All networking components must be designed to meet the proper bandwidth and latency requirements for any planned site-to-site and intra-data center network traffic.
