CHOReOS will implement service middleware support, effectively enabling the deployment of adaptable, QoS-aware choreographies in the ULS Future Internet, integrating and further evolving the latest research advances in the area of Grid and Cloud computing, Enterprise Service Bus (ESB), and pervasive computing. Service-oriented middleware enables adaptable choreographies over ESB-based middleware, Grids, Clouds, and technologies for the Internet of Things, thus overcoming scalability and heterogeneity issues of the Future Internet.
