| Summary: | A QoS preference-aware replica selection strategy for a kind of users with individual QoS sensitivity（IQS） constraints in cloud computing datacenters was put forward in advance.According to the QoS requirements of data ser-vices from IQS users,a novel three-dimensional QoS model of replica selection was introduced,and a QoS prefer-ence-aware algorithm based on analytic hierarchy process（AHP） named QoPA was proposed to deal with the IQS con-straints.In order to evaluate the replica sites in datacenters and provide the best of them to the IQS users,an algorithm for replica selection based on fuzzy comprehensive evaluation termed FCE<sub>R</sub>S was designed and implemented.Results of experiments show that the FCE<sub>R</sub>S can serve the various IQS users in cloud computing very well by providing reason-able replica strategies effectively. |
