1. A method comprising:
configuring, by a controller for a virtualized computing infrastructure, a plurality of Virtual Extensible Local Area Network (VXLAN) segments in a switch fabric, 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
assigning, by the controller and to the first VXLAN segment, a plurality of floating IP (FIP) addresses for configuring overlay networks of the plurality of overlay networks configured in the first subset of the host computing devices.
