Abstract: A system for providing a virtual data storage medium according to an embodiment of the invention may be a system for providing a virtual data storage medium using data storage federation, where the system may include: heterogeneous data storage media including a multiple number of data storage media using different interfaces, protocols, and commands for using stored data; and a federation unit configured to generate a virtual data storage medium by federating the heterogeneous data storage media.

Abstract: A method for performing policy-based storage service federation can include: identifying whether or not a policy is applicable for a request received from a client by a request interceptor; obtaining a policy by evaluating request information relating to the request and a policy status; and obtaining a customized set of storage services based on the policy. The method can provide a framework corresponding to a storage federation layer to allow fast application development.

Abstract: Disclosed is a cloud computing system that includes: a core cloud part that stores and manages the cloud service in the core cloud server; and an edge cloud part that is arranged on a network node connected with the client terminal to form an edge cloud server, operates a portion or an entirety of a cloud service of the core cloud part at the edge cloud server, and stores and manages data of said service or receive cloud service packet information from the core cloud part to provide the cloud service to the client terminal. The edge cloud part includes an edge cloud awareness part that determines whether or not identification is possible for a cloud service request signal transmitted from a publisher client terminal, and an edge cloud processing part that determines whether or not to provide the cloud service corresponding to the request signal.
