1. A method comprising:
configuring, by an underlay network controller for a virtualized computing infrastructure, a plurality of Virtual Extensible Local Area Network (VXLAN) segments in a switch fabric, the switch fabric comprising network switches for the virtualized computing infrastructure, thereby enabling orchestration of respective tenants in the plurality of VXLAN segments,
wherein each VXLAN segment of the plurality of VXLAN segments provides underlay network connectivity among a different subset of host computing devices of the virtualized computing infrastructure, and
wherein a plurality of overlay networks are configured in a first subset of the host computing devices having underlay network connectivity by operation of a first VXLAN segment of the plurality of VXLAN segments, thereby enabling orchestration of multiple subtenants of a first tenant in the first subset of the host computing devices; and
provisioning, by the underlay network controller and for the first VXLAN segment, a Source Network Address Translation (SNAT) gateway between a VXLAN Tunnel Endpoint (VTEP) of the first VXLAN segment and the plurality of overlay networks of the first VXLAN segment.
