摘要:
A system for providing resources of a cloud infrastructure is provided. In the system, a client terminal may dynamically span its storage to heterogeneous cloud storages as necessary. A client determines, when receiving a file access request from an application, whether to process the file access request as a local file access request for access to a local storage of the client or as a cloud file access request for access to a cloud storage connected through the Internet. A brokerage server receives the file access request and supports the client by brokering a connection to a cloud infrastructure in response to the file access request.

Provided are an apparatus and method for providing services using a virtual operating system (OS). The apparatus classifies virtual resources into a plurality of mutually exclusive regions and manages the virtual resources based on the provides services regions. The plurality of provides services regions include a virtual region whose resources are stored in and used on an external storage, and an overlay region whose resources refer to host resources. The apparatus uses the region information for virtual resources and a list of resources accessed for each application process to manage the virtual resources.

A method and apparatus for inputting and outputting data by using a virtualization technique are provided. The method includes generating a virtual operating system (OS) for the external device, which is connected to a host, based on OS information stored in the external device, setting a partial area of a storage of the host as virtual storage for the external device, and storing the data in the virtual storage or a memory of the external device in response to a request for inputting and outputting the data from the virtual OS.

摘要:
A management server and method for providing a cloud computing service at high speed and reasonable cost, are provided. The management server provides a virtual machine to a client as a computing resource. The virtual machine is multiplexed by operating multiple virtual devices on a single virtual machine. Accordingly, demand for computing resources may be predicted in advance and may be provided to a user more efficiently.
