Abstract: The claimed subject matter provides a system and/or a method that facilitates creating a composite application. A model architecture component can model a business rule utilizing at least one node in a novel hierarchical structure. A run-time engine can automatically create a complex, long-running composite application based at least in part upon the hierarchical node structure such that representative process segments of the application are invoked by the business rule which, in turn, is invoked by internal, externally generated, asynchronous events.

Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating integration and communication of cloud services and enterprise applications. The disclosed aspects include identifying a port opened by an integration device within an on-premise system to communicate with a cloud system. A persistent connection with the cloud system is maintained via this port so as to provide on-premise access to the cloud system via the integration device, including access to at least one different device within the on-premise system. Aspects for facilitating a bidirectional communication of distributed objects between an on-premise system and a cloud system are also disclosed. Here, on-premise objects residing within the on-premise system are abstracted, and requests from the cloud system to invoke the on-premise objects are facilitated. Similarly, cloud objects residing within the cloud system are abstracted, and requests from the on-premise system to invoke the cloud objects are facilitated.
