Remus: a Restful Marketplace for Unified Services Ralph Vigne

Today's companies more and more embrace the utilization of inter-organizational services as part of their internal business processes. The benefit from this outsourcing is manifold, ranging from lower maintenance burden to predictable cost. One problem is, that for companies in order to not bind themselves to a single service provider, they have to ensure that the services they consume are interchangeable. Therefore a marketplace for services, based in a common set of rules, that allows companies to stay flexible when selecting business partners is needed. In this thesis we introduce a hybrid process and service repository acting as a base for such a marketplace. Organizing services into different application domains with a common interface allows easy usage of the provided services for the customers, while the support of interface transformation within service description keeps the vendors flexible. We further introduce a prototype system demonstrating how to use this information in combination with adaptive workflow execution engine and Cloud infrastructures as a base. To proof the feasibility of the introduced concepts, a mobile client executing a real-world example is introduced.
