Abstract

Model-driven engineering (MDE) techniques are increasingly being used to address many of the development and operational lifecycle concerns of large-scale component-based systems. One such concern lacking significant research deals with the validation of quality-of- service (QoS) properties of component-based systems throughout their development lifecycle instead of waiting until system integration time, which is very late and can be detrimental to project schedules and costs. This paper describes our novel MDE-based solution to address this challenge. At the core of our solution approach are (1) a set of domain-specific modeling languages that allow us to mimic component "business logic," and (2) a generative programming framework that synthesizes empirical benchmarking code for system emulation and continuous QoS evaluation.
