In some examples, a computing device comprises a first service function instance to apply a service function and a service function forwarder to: receive a first layer 3 routing protocol route advertisement that includes service function instance data for a second service function instance, the service function instance data indicating a service function type and a service identifier for the service function instance; receive a second layer 3 routing protocol route advertisement that includes service function chain data for a service function chain, the service function chain data indicating a service path identifier and one or more service function items; and send, to the second service function instance and based at least on determining a service function item of the one or more service function items indicates the second service function instance, a packet classified to the service function chain.

Distributing service function chain data and service function instance data in a network

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.

A method for configuring a fabric managed by a software-defined networking (SDN) controller includes, with a first control host installed in a first rack having a first management switch and a second control host installed in a second rack, executing controller nodes that implement an SDN controller using a controller virtual network extending between the first rack and the second rack. The first management switch is configured to route traffic between the controller virtual network and a device management network extending from the first management switch to a fabric network device of the fabric managed by the SDN controller. The method further includes configuring, with the SDN controller, via the first management switch, the fabric network device with the controller virtual network to enable communications, via the controller virtual network, between the first control host and a compute node or a storage node connected to the fabric network device.

Network controller deployment

An example method includes receiving a resource request for at least one compute and/or storage resource from a distributed computing system distributed among multiple data centers, determining a resource policy that is associated with the resource request, wherein the resource policy includes a rule specifying at least one metadata tag and at least one criterion associated with the at least one metadata tag, identifying at least one object included in a resource object model that complies with the rule of the resource policy, wherein the at least one object has an assigned value for the metadata tag that satisfies the at least one criterion, selecting a data center that is associated with the at least one object identified from the resource object model, and deploying, on the selected data center, the at least one compute or storage resource.
