An Active DBMS Style Activity Service for Cloud Environments
The authors propose an activity service as a component in cloud computing with the particular novelty that they base this service on the well-defined and proven semantics of Active DataBase Management Systems (Active DBMS). In addition, they utilize well-known principles of service oriented architectures. Furthermore, they 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 implement agility and self management of cloud applications. As contribution of this paper, they provide the high-level design of this activity service.
