A Model of Green Replication in Cloud Computing Environments
Cloud computing provides geographically distributed resources.However,ensuring efficient and fast access to such huge and widely distributed resources is hindered by the high latencies of the Internet.Replication is adopted to address these problems,but leads to energy increase.Aimed to replica creation and green computing,we introduce a model to decide replica creation opportune moment,which is based on queuing theory.Through statistical record of the arrival rate of uses,service period,and replicas already created,calculating length of queue,waiting duration time,busy period,service strength and so on,a reasonable creation opportune moment of replica can be obtained.Analysis and experiments,the results prove that the replication strategy is predictable,saving energy and improving the service rate of users” requests.
