The proposed poster presents on-going research to define the basic models and architecture patterns for federated access control in heterogeneous (multi-provider) multi-cloud and inter-cloud environment. The proposed research contributes to the further definition of Intercloud Federation Framework (ICFF) which is a part of the general Intercloud Architecture Framework (ICAF) proposed by authors in earlier works. ICFF attempts to address the interoperability and integration issues in provisioning on-demand multi-provider multi-domain heterogeneous cloud infrastructure services. The poster will describe the major inter-cloud federation scenarios that in general involve two types of federations: customer-side federation that includes federation between cloud based services and customer campus or enterprise infrastructure; and provider-side federation that is created by a group of cloud providers to outsource or broker their resources when provisioning services to customers.

The proposed federated access control model uses Federated Identity Management (FIDM) model that can be also supported by the trusted third party entities such as Cloud Service Broker (CSB) or trust broker to establish dynamic trust relations between entities without previously existing trust. The research analyses different federated identity management scenarios, defines the basic architecture patterns and the main components of the distributed federated multi-domain Authentication and Authorisation services/infrastructure.

The proposed solution intends to provide an architectural and operational basis for the trusted third party services that can be provided by the Open Cloud eXchange (OCX), a newly proposed concept by GN3Plus JRA2 activity as a way to solve the problem of delivering cloud services to campus users.

The presented work targets to provide an architectural model for developing intercloud middleware and in this way will facilitate cloud interoperability and integration.
