Abstract
Web based information systems are exposed to various dependability issues during their lifetime. Reconfiguration is then used by the administration to ensure continuity of service. Such forced reconfigurations can cause unforeseen side-effects, such as server overloading. To prevent this, it is proposed to use simulation techniques to analyze the reconfigurations and construct a safe reconfiguration strategy. Extensions to the available network simulation tools are proposed to support this. The authors present the results of multiple experiments with web-based systems, which were conducted to develop a model of client-server interactions that would adequately describe the relationship between the server response time and resource utilization. This model was implemented in the simulation tools and its accuracy verified against a testbed system configuration.
