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.
