High performance computing infrastructures, such as the Grill, have become available to several scientific communities but their use is often limited due to the high level of technical detail needed tor the successful deployment of applications. The next step tor supporting e-scientists is to provide them with an e-science environment that comprises high level services which may be easy and directly usable while hiding the underlying infrastructure. Towards this aim, the paper proposes to extend the use of solutions developed tor business environments and in particular the adoption of a Service Oriented Architecture. AD architectural model for the deployment of scientific workflows is presented as well as a case study to validate the effectiveness of the proposed approach.
