Nowadays, different eScience actors are assuming the Federated Cloud as a model for the aggregation of distributed cloud resources. In this domain, an open problem is about service delivery and resource usage in complex environments, with multiple users and communities which are committed with particular policies in the use of the federated resources. In the other hand, DIRAC has become a multi-community middleware fully interoperable in Distributed Computing Infrastructures (DCI), including several cloud managers. Furthermore, DIRAC is able to federate Infrastructure as a Service (IaaS) to provide Service as a Service (SaaS) in a transparent manner to the final user. This paper presents a credit model for the resource usage providing automatic management in federated cloud. A prototype implementation with DIRAC is also described, including a test for the model assessment and drawing up conclusions for a production level federated cloud governance with DIRAC.
