Abstract—Cloud federation is a new paradigm in Cloud Computing. One of the major advantages of this paradigm resides on its ability to help the Cloud Service Provider (CSB) overcome the limitation of their own resources in order to serve their clients. In view of a vast diversity of cloud services being offered by several providers in the cloud federation, it becomes a necessity to couple this paradigm with an automatic negotiation to dynamically form the best possible offer to the clients requirements. In this paper, we propose an extension for the Open Cloud Computing Interface (OCCI) to support the automatic negotiation between different cloud providers using the Contract Net Protocol (CNP) involved in Multi-agent-System (MAS). In order to prove the efficiency and the effectiveness of our approach, we suggest a real case study illustrating how a client can interact with our approach. In addition, we implement a prototype to evaluate the key idea presented in this paper through a set of experiments.
