An efficient resource allocation scheme for cross-cloud federation

In order to provide uninterrupted services to the cloud clients from cloud vendors with finite resources, it is important to get as more computing and storage resources as possible and at the same time achieve network or computing load balance. In this study, we focus on the computing resource allocation involving with the management of processing power, network transmission and storage resource. A manager frame is defined for cloud and identity provider, and a cross-IDP and cross-cloud federation architecture based on inter-trust context is also presented. In this method, we elaborate a procedure of borrowing available virtualized resources from external clouds via a constructed federated cloud.
