Abstract—We propose an activity service as a component in cloud computing with the particular novelty that we base this service on the well-defined and proven semantics of Active Database Management Systems (Active DBMS). In addition, we utilize well-known principles of service oriented architectures. Furthermore we aim to provide an integration with a cloud service mediation component to automatically react to changes occurring in the cloud environment and in this way to imple-ment agility and self management of cloud applications. As contribution of this paper we provide the high-level design of this activity service. This includes architecture, core interfaces and a semantically well-defined rule and execution model, based on extended Active DBMS semantics.
