Techniques are disclosed for scalable virtualization of tenants and subtenants on a virtualized computing infrastructure. In one example, a first controller for the virtualized computing infrastructure configures underlay network segments in the virtualized computing infrastructure by configuring respective Virtual Extensible Local Area Network (VXLAN) segments of a plurality of VXLAN segments of a VXLAN in a switch fabric comprising network switches. Each VXLAN segment provides underlay network connectivity among a different subset of host computing devices of the virtualized computing infrastructure to enable orchestration of multiple tenants in the VXLAN. A second controller for a first subset of the host computing devices has underlay network connectivity through operation of a first VXLAN segment. The second controller configures overlay networks in the first subset of the host computing devices to enable orchestration of multiple subtenants in the first subset of the host computing devices.

An apparatus includes a first communication interface configured to be communicatively coupled, via an optical line, to a network device that is disposed in an optical network using wavelength division multiplexing (WDM). The apparatus also includes a second communication interface configured to be communicatively coupled to a router via an Ethernet connection. The apparatus also includes a signal generator operatively coupled to the first communication interface and the second communication interface. The signal generator is configured to generate an Ethernet signal representing at least one attribute of the optical line between the first communication interface and the network device. The second communication interface is configured to transmit the Ethernet signal to the router.
