The QoGS Method Application for Selection of Computing Resources in Intercloud
Keywords:Cloud, load flow control, computer networks
AbstractIn this paper the selection of the right Cloud in Intercloud of computing services for fulfilment of the user task is analyzed. The main problem approached is how to select the right Cloud in Intercloud for the user task when there are no available or relevant resources in the private and public Cloud. In this case the Cloud, which gives the calculation results to the user in the shortest time including waiting time in queue, should be selected. For selection of the right Cloud the QoGS method has been chosen. The principle schema of QoGS method application in Intercloud has been presented. However, QoGS method works properly if the right set of weighted coefficients (SoWC) is selected. Existing methods are not suitable for selection of weighted coefficients because they require sending a lot of test tasks to Intercloud. Therefore, a new algorithm for selection of the best SoWC is presented. Results of the experiment show that it allows minimizing the workload of Intercloud by test tasks significantly.
