SaaAS - The mobile agent based service for cloud computing in internet environment

Current cloud computing systems always focus on the high bandwidth local area network environment, for example, an LAN of a corporation. This paper uses mobile agent to implement the software and data service for cloud user in Internet environment, and make the cloud computing system adaptable to work in Internet environment, such as an international corporation with branches all over the world. The works in this paper includes three parts: (1) introducing mobile agent into cloud computing system and presenting the mobile agent based service for cloud computing system: Service as an Agent Service (SaaAS). The SaaAS uses mobile agents as the underlying facility to offer the service for user; (2) presenting a high performance code and data of service load mechanism based mobile agent for SaaAS, which can effectively reduce the heavy communication overhead in Internet; (3) presenting a novel data coherence mechanism for SaaAS: Divided-Cloud and Convergent Coherence Mechanism (DCCM). The application of mobile agent enables SaaAS to be more suitable to work in Internet environment than conventional cloud computing system.
