Cost-driven cloud storage model based on mobile agent

Considering replica strategy of cloud storage solutions,the cloud service confronts challenges to pursue business benefit.This paper presents a cost-driven cloud storage model based on mobile agent,introduces business concepts and expressions,proposes an adaptive mobile agent strategy.Mobile agents with replicas move,copy or destroy in the heterogeneous cloud platform,so the cloud storage can improve load balance and maximize its profits.Last the algorithm is presented.Experiments illustrate that this model is superior to traditional static replica strategy at both load balance and profits.
