Federated networking services in multiple openstack clouds

Cloud federation refers to a mesh of Cloud providers that are interconnected by using agreements and protocols necessary to provide a decentralized computing environment. Federation is raising many challenges in different research fields but is also creating new business opportunities. Nowadays, the combination between Cloud federation, Software Defined Networking (SDN), and Network Function Virtualization (NFV) technologies offers new business opportunities to Cloud providers that are able to offer new innovative federated Cloud networking services to customers. In this paper, we focus on federated Cloud networking services considering multiple OpenStack Clouds. In particular, we present a preliminary outcome of an innovative design of a Federation Management system acting as an external service provider dealing with federated networking services among multiple federated OpenStack Clouds. More specifically, we describe how virtual resources, virtual networking, and security management can be accomplished.
