Enterprises use the cloud for unlimited resource, scalability and elastic provisioning along with being able to use state of the art commodity or specialized solutions available in the cloud. The challenge of this vision is the proper and safe integration of on-premise IT-Landscapes with data and applications in the cloud. To find solutions for integration of classical and cloud environments two approaches, top-down and bottom-up, were used. In the top-down approach cloud integration patterns were specified based on scenarios. In the bottom-up approach cloud integration patterns were based on case study application requirements. Results of this paper are novel cloud integration patterns for various cloud integration scenarios.
