Broker-based Cross-Cloud Federation Manager

Abstract

Cloud federation is the next step in creating a new cloud computing ecosystem. The absence of suitable business models for federation managers is hindering the wide deployment of this critical feature. In this paper we will study existing federation managers, specifically CCFM (Cross-Cloud Federation Manager) and analyze its strengths and limitations. To overcome its limitations and make cloud federation more competitive in the current business trends, we introduce a new node called "broker" which will play a significant role in the enhanced CCFM mechanisms. The discovery and match-making agents in CCFM wil be modified to enforce a new business model which is more interesting for private investors. Finally, our new business model will be discussed and possible versions are stated.
