Abstract: A method of deploying a network service (NS) across multiple data centers includes identifying virtual network functions (VNFs) associated with the NS in response to a request for or relating to the NS, generating commands to deploy VNFs based on VNF descriptors, and issuing the commands to the data centers to deploy VNFs. The data centers each have a cloud management server in which cloud computing management software is run to provision virtual infrastructure resources thereof for a plurality of tenants. The cloud computing management software of a first data center is different from the cloud computing management software of a second data center, and the commands issued to the first and second data centers are each a generic command that is not in a command format of the cloud computing management software of either the first data center or the second data center.

Abstract: A method of deploying a virtual network function of a network service in a data center having a cloud management server running a cloud computing management software to provision virtual infrastructure resources of the data center to at least one tenant, includes generating at least first and second API calls to the cloud computing management software in response to external commands received at the data center to deploy a virtual network function, and executing at least the first and second API calls by the cloud computing management software to deploy the virtual network function. The cloud computing management software creates at least one virtual machine by executing the first API call and at least one virtual disk by executing the second API call.

Abstract: A method of deploying a network service across multiple data centers, each having a cloud management server running a cloud computing management software to provision virtual infrastructure resources thereof for a first tenant among a plurality of tenants, includes maintaining for each data center static inventory data that indicate virtual infrastructure resources that are available thereat to the first tenant, identifying, in response to a network service request for the first tenant, a virtual network function associated with the network service, generating commands to deploy the virtual network function based on a descriptor of the virtual network function, selecting one of the data centers in which the virtual network function is to be deployed based on the descriptor of the virtual network function and the static inventory data of each data center, and issuing the commands to the selected data center to deploy the virtual network function.
