The MEADEP
(Measurement-based Dependability) software tool was developed by SoHaR
for the measurement, modeling, and prediction of dependability in complex systems.
This paper describes how MEADEP can be used
1.assess a large web site,
2. identify the subsystems where the greatest improvement can be achieved, and
3. answer business questions related to service level agreements.
The paper shows how important, non-obvious conclusions can be reached through modeling.
Two examples are to identify the subsystem that can benefit most from reliability
improvement and the most important parameter to negotiate in a service level agreement
in order to maximize uptime. The paper also shows how critical business decisions
can be reached through such modeling.
