Title
Load distribution among replicated Web servers: a QoS-based approach
Abstract
A dominant factor for the success of an Internet based Web service is the Quality of Service (QoS) perceived by its users. The principal QoS attributes these users perceive include those related to the service "responsiveness", i.e. the service availability and timeliness. In this paper, we argue that QoS can be provided by distributing the processing load among replicated Web servers, and that these servers can be geographically distributed across the Internet. In this context, we discuss strategies for load distribution, and summarize a number of alternative architectures that can implement those strategies. The principal figure of merit we use in order to assess the effectiveness of the load distribution strategies we discuss is the response time experienced by the users.
