A network system having a pool of network resources including aggregation routers in communication with a wide area network, aggregation switches in communication with the aggregation routers, and groups of servers, each group having a corresponding switch. The network system includes a cloud provisioning system to receive a cloud provisioning request from and end user, the cloud provisioning system including an orchestrator to form, from the pool of network resources, a plurality of overlay networks which together form the cloud, to form each overlay network, the orchestrator, for one or more groups of servers, to logically assign, in a one-to-one fashion, ports of servers to ports of the corresponding switch, and to logically assign the corresponding switch of the one or more groups of servers to ports of a same aggregation switch, and an internet protocol address management (IPAM) module to assign an IP address to each overlay network at the aggregation routers. |
