Internet of Things (IoT) is an exhortation defining next generation networks. Though it is an emerging field pertaining to a little over a decade and a lustrum old, it has already started penetrating in a layman’s life in one way or the other. The technology is dynamic and self-adapting and surprises masses with its increasing applications. This paper will provide a bird view insight on IoT design methodology through case studies on designing of an IoT system for monitoring Wind Turbine failure and contactless health monitoring system and cold chain delivery of vaccine/medicines. As IoT is technology independent, understanding of mapping of functional groups (of the system to be automated) to operational view is enviable. SAP Leonardo is used for prototype automation, benefitting its micro-services which in turn enable to leverage future facing technologies.
