Usage Control in Cloud Federations

Cloud Federation is a promising approach to enhance cross-cloud application execution, nevertheless it highlights many challenges still not completely solved in Cloud Computing, such as vendor lock-in or authorization revocation for long-lasting resources. In this paper we focus on authorization and enhance the Cloud Federation paradigm by introducing the support of  Usage Control (UCON), an approach that, by continuously monitoring the right of using resources, allows for immediate revocation as soon as the conditions granting the access right are no longer valid. We implemented a real prototype of a Cloud Federation framework on the basis of the UCON model and performed some tests on the overhead caused by different security policies and request distributions. Results suggest that performances are sustainable for large federated platforms.
