Abstract: It is a tendency that we use parallel Web server cluster to provide high quality Web service. This technology have some character that is high performance and available and low cost This paper introduces some structure and key technique of the Web server cluster. Based on this .we design a kind of scalable Web server cluster that provides differentiated service .We give the structure description and the strategy of resource management.
