Load Balancing Approaches for Web Servers: A Survey of Recent Trends

Numerous works have been done for load balancing of web servers in grid environment. Reason for popularity of grid environment is to allow accessing distributed resources which are located at remote locations. For effective utilization, load must be balanced with all resources. Importance of load balancing is discussed by distinguishing the system between without load balancing and with load balancing. Various performance metrics that needed to be considered for designing an efficient load balancing algorithm are also described. Intensive review of literature of different load balancing approaches for web servers had been carried out and presented in this paper.
