Abstract: A computer-implemented method includes receiving a network configuration request from a site manager, the network configuration request including location information of a site of the network, identifying a geographic domain that includes the network site based on the location information, identifying a server cluster mapped to the geographic domain, determining whether a network function exists in the server cluster and is capable of managing the network, and either using the existing network function to configure the network based on determining that a network function exists in the server cluster and is capable of managing the network, or creating a new network function in the server cluster and using the new network function to configure the network based on determining that no network function exists in the server cluster and is capable of managing the network.
