395 The Cloudgrid Case Study Valentina Casola University of Naples "Federico II", Italy Antonio Cuomo University of Sannio, Italy Umberto Villano University of Sannio, Italy Massimiliano Rak Second University of Naples, Italy Access Control in Federated Clouds: Chapter 20 ABSTRACT Resource sharing problem is one of the most important aspects of Cloud architectures whose primary goal is to fully enable the concept of accessing computing resources on-demand. Access control and resource federation are hot research topics and a lot of open issues should be addressed on function- alities, technological interoperability, quality of services and security of the federated infrastructures. This chapter aims at offering a view on the problems of access control on federated Clouds; since they strongly depend on chosen architectures and platforms, the chapter will discuss some solutions applied on a real case study: the PerfCloud framework, which is based on the integration of Grid and Cloud platforms. The proposed architecture is based on the adoption of an interoperability system to cope with identity federation and access control, it is strictly related to the adopted framework nevertheless it helps the reader to have an idea of the involved open issues and available solutions in commercial or experimental clouds.
