An apparatus and method provide a cloud brokerage service based on multiple cloud-computing systems. The method includes receiving, by a cloud service broker, a request for a cloud service from a cloud service client, the cloud service broker being connected with the multiple cloud-computing systems, providing, by the cloud service broker, a cloud service brokerage based on cloud services of the multiple cloud-computing systems, the cloud service brokerage enabling the cloud service complying with the request to be provided to the cloud service client, transmitting, by the cloud service broker, a control request for the cloud service to one or more cloud-computing systems of the multiple cloud-computing systems, and controlling, by the cloud service broker, a status of the cloud service after the cloud service broker receives an acknowledgment for the control request from the one or more cloud-computing systems.

Apparatus for providing cloud service using cloud service brokerage based on multiple clouds and method thereof

Disclosed herein are an apparatus and method for providing a cloud brokerage service based on multiple clouds. The method includes receiving, by a cloud service broker, a request for a cloud service from a cloud service client, the cloud service broker being connected with the multiple cloud-computing systems; generating, by the cloud service broker, the cloud service complying with the request based on one or more services registered in a service catalogue of the cloud service broker; newly registering, by the cloud service broker, the generated cloud service in the service catalogue; and providing, by the cloud service broker, the newly registered cloud service to the cloud service client.

Apparatus for providing cloud brokerage service based on multiple clouds and method thereof

Disclosed herein are an apparatus and method for providing a cloud service based on cloud service brokerage. The method includes receiving, by a cloud service broker, a first request for a cloud service from a cloud service client, wherein the cloud service broker is connected with the multiple cloud-computing systems; providing, by the cloud service broker, a cloud service brokerage based on cloud services of the cloud-computing systems, wherein the cloud service brokerage enables the cloud service complying with the first request to be provided to the cloud service client; and monitoring, by the cloud service broker, a service level of the cloud service during provision of the cloud service and controlling, by the cloud service broker, the cloud service such that the service level satisfies conditions of the first request.

Apparatus for providing cloud service based on cloud service brokerage and method thereof

Disclosed herein are apparatus and method for validating service control status. The apparatus for validating service control status includes a service control request unit for requesting control of a service from a computing system, a service control status checking period generation unit for generating a service control status checking period in order to check completion of the service control, and a service control status checking communication unit for performing service control status checking communication with the computing system based on the service control status checking period.

Apparatus and method for validating service control status

Disclosed herein are an apparatus and method for virtualizing Input/Output (I/O) devices. The apparatus includes a hardware device control unit, a guest Operating System (OS) unit, a virtual machine monitor unit, and a host OS unit. The hardware device control unit controls the I/O devices of a terminal. The guest OS unit runs a guest OS via a virtual machine. The virtual machine monitor unit includes shared memory and an event channel, stores an instruction and data, and transfers the stored instruction and the data to a host OS. The host OS unit performs the operation of assigning the shared memory to the virtual machine monitor unit, the operation of generating the event channel, and an operation corresponding to the I/O instruction, stores the results of performance of the operations, and performs control so that the results of the performance of the operations are sent to the guest OS unit.

Apparatus and method for virtualizing input/output devices using shared memory in host-based mobile terminal virtualization environment

Provided are a virtualization based high availability cluster system and a method for managing failures in a virtualization based high availability cluster system. The high availability cluster system includes a plurality of virtual nodes, and a plurality of physical nodes each including a message generator for generating a message denoting that the virtual nodes are in a normal state and transmitting the generated message to virtual nodes in a same physical node.
