The enablement of the Grid paradigm for commercial solutions is a fundamental issue for both research bodies and companies. Different technologies seem to be mature to serve the purpose, but still research and experimentation is needed. In fact, the introduction of the business aspect poses new challenges such as new business models, service composition, relationships management, etc. In this paper, we present the S-Sicilia project, a 2-year collaboration between Oracle and the COMETA consortium, aiming to setup a Grid-based business infrastructure to provide business services with guaranteed QoS for companies. The system does not aim to provide answers for all business related issues, but rather be a kind of benchmark where experimentation on real cases takes place.
