On the Complexity of Cloud and IoT Integration

Cloud Computing and the Internet of Things (IoT) shift from trend technologies to well established and broadly accepted means to foster business development and service quality. For utilising their full potential in the context of complex systems, applications based on these technologies often have to be properly integrated resulting in major challenges. In this paper, we provide means for better understanding possible occurrences of integration challenges when establishing Cloud and IoT systems. We briefly present several existing Cloud and IoT architectures and a survey on existing integration challenges. Based on these results, we derived an overall integration architecture as a supporting tool for the indication of the different integration challenges, which is presented in a short and full version due to the overall complexity. At last, some general approaches for integration are discussed.
