In order to solve the problem of replica selection for a kind of user with individual QoS sensitivity in cloud environment, a strategy is presented based on individual QoS sensitivity constraints with comprehensive consideration of the system loading, transmission cost, user’s QoS preference and historical evaluation information. On the basis of it, the strategy considers the similarity of current demanding environment and the historical replica credibility evaluated envrionment, and then selects the special replica. Simulation experiment results testify that the selection strategy is feasible and effective.
