1. An information and communication technology (ICT) resource management device that manages a physical node and a virtual node as ICT resources, the ICT resource management device comprising:
a configuration information management circuit configured to manage physical layer configuration information that is information on a configuration of the physical node on a physical layer and virtual layer configuration information that is information on a configuration of the virtual node on a virtual layer;
a layer mapping circuit configured to perform mapping between the physical layer and the virtual layer;
a location specifying circuit configured to specify a location of the physical node included in the physical layer configuration information;
a first device connect destination determination circuit configured to determine a first physical node that is to be a connection destination to which a device utilizing a service is to be connected, based on at least any one of the specified location, service management information that is managed as information on the service, a network connection configuration of a network connecting the device utilizing the service to the first physical node determined to be the connection destination, and quality of the network in response to a request for configuration change regarding a connection of the device utilizing the service to the first physical node determined to be the connection destination;
a blueprint creation circuit configured to create a blueprint in response to the request for the configuration change, which blueprint is design information on an infrastructure required for the configuration change, based on the physical layer configuration information, the virtual layer configuration information, mapping information that is information obtained as a result of the mapping, and the connection destination; and
an orchestrator circuit configured to access and run a program that is operable via a southbound application programming interface (API), based on the blueprint, to thereby perform orchestration to the virtual layer, wherein the service management information includes information about an application utilized and about an operating ICT resource containing an identifier of the ICT resource that operates when a target service is provided.
