A Mechanism for Improving Web Server Performance Using Fuzzy Concept

This paper presents a mechanism to improve Web server performance with fuzzy-based techniques. A load balancing mechanism based on the fuzzy control technique is developed in such a way that ambiguous situations caused by workload estimation of cluster- based Web servers, client request rates, and dynamic request rates can be represented in an effective way. Extensive experiments show that the fuzzy-based performance isolation technique improves the performance of Web servers in terms of the 95- percentile response times.
