Cloud Computing builds on the latest achievements of diverse research areas, such as Grid Computing, Service-oriented computing, business processes and virtualization. In this paper, the authors reveal open research issues by envisaging a federated cloud that aggregates capabilities of various IaaS cloud providers. They propose a Federated Cloud Management architecture that acts as an entry point to cloud federations and incorporates the concepts of meta-brokering, cloud brokering and on-demand service deployment. The meta-brokering component provides transparent service execution for the users by allowing the system to interconnect the various cloud broker solutions available in the system. Cloud brokers manage the number and the location of the utilized virtual machines for the received service requests.
