Abstract

The rapid advancement and deployment of Web services call for a precise yet simple model for capacity planning and analysis purposes. The most widely deployed Web services architecture is the 3-tiered system, which is composed of a front-end Web server, an application server and a backend database server. In this paper, we present an analytical model of the 3-tiered Web services architecture. We show by using queueing network theory, we can model the 3-tiered Web services architecture accurately. A testbed is built to measure model parameters based on industry standard server components and TPC-W benchmark. Validation results show the proposed model predicts performance measures such as response time and throughput accurately.
