Abstract
Performance of web service may fluctuate due to the dynamic Internet environment, which makes the Quality of Service (QoS) inherently uncertain. It is necessary to reconfigure the web service to enable its QoS values to meet users’ demands. In this paper, we propose an efficient and effective dynamic substitute approach based on cloud model. Our approach employs cloud model to compute the QoS uncertainty to determine dynamic substitute targets. By targeting substitutions, the reconfigured web service will better satisfy users’ requirements. Both theoretical analysis and experiment results have proven the feasibility and effectiveness of the approach.
