A sevice-oriented broker for bulk data transfer in cloud computing

Cloud computing emerges as new computing paradigms in which virtualized resources provide reliable and guarantee service for users demand. Actually, cloud is a service-oriented platform because all kind of virtual resources are treated as service to users. Nowadays, most of data-intensive applications have been developed on cloud system. These applications reaches geographically separated storage or data resource with even cross-continental-networks. Then, the performance degradation of networks will surely affect the cloud application performance and user request. In order to ensure guarantee service of bulk data transfer in cloud computing, the reservation and combined resources utilization become critical issues which include data and network resources. This issue involves reserve and assign combined resources to meet user's QoS requirement. According to this problem, a cloud infrastructure service framework (CISF) is proposed to achieve guarantee service for data-intensive applications in this paper. And a service-oriented resource broker (SRB) based on this framework which is proposed to discovery, select, reserve and assign best combined resources. Finally, under user's QoS constraint dynamic resource selection algorithm has been implemented for optimization of combined resources allocation
