On the development of IoT systems

A typical IoT system consists of four distinct architectural elements: devices, gateways, cloud and apps. All these elements require special skills in their development. In order to write safe, secure IoT systems, developers must be trained and experienced in four different areas of software development: embedded, cloud, web and mobile. In addition, given the distributed nature of IoT systems, distributed programming skills play a critical role. In this paper we examine the challenges in IoT system development, and summarize our observations and experiences on the necessity and co-presence of different types of software development skills in the design of IoT systems.
