Multitenant cloud network fabrics can be constructed by implementing network virtualization in one of two manners; either by programmatically configuring the physical network via an SDN controller, or – as in the case of this solution brief – by deploying Network Virtualization Overlays (NVO), aka tunnels, where the tenant tunnels are abstracted from the physical network and all the complexity is pushed to the compute edge. In that case, the physical network becomes a simplified IP forwarding engine.

This Solution Brief focuses on the use of NVOs and the associated underlay network solutions from Dell EMC Networking.
