Architectures and emerging trends in Internet of Things and Cloud computing: a literature review

The Internet of Things (IoT) enables interconnection between different types of devices using information and communication technologies. This interconnection generates a large amounts of data that require transmission, analysis and storage. The benefit of Cloud Computing has extended the capacities of devices since they are limited in terms of storage capacity and computing power. In order to ensure the integration between IoT and Cloud Computing, different architectures of an IoT system in a cloud environment have been proposed. The purpose of this article is to present these architectures, expose a synthesis of them to find out their emerging trends, and also to identify the layers that are common to them. The results presented are mainly the identification of these layers, and the emerging trends in IoT systems in a cloud environment, which aim mainly to bring the cloud resources more closely to devices, in order to reduce latency.
