Abstract The present invention provides a systems and methods for modelling and predicting the performance and scalability of information systems. The parts of the system are a domain specific performance modelling language, a graphical modelling interface, a module for managing models, a transformation module for converting graphical models into simulation models, a simulation engine and associated metrics calculation modules, and a simulation graphical interface. The system provides a graphical tool for creating performance models of a plurality of components of information systems, including workloads, simple and composite services, workflows and servers. Each component may be associated with a plurality of measured or experimental performance parameters. The system provides a transformation engine to automatically convert graphical performance models to run-time simulation models, and provides a discrete event simulator to process the run time simulation models and to compute a plurality of predicted performance and scalability metrics which are graphically displayed. 7o Q CD CDC~l Q f~',CD CD' vmum |
