As the marketplace ponders how best to incorporate fog computing into the Internet of Things (IoT), one of the most important challenges we face is figuring out exactly how fog will be used. Studying potential use cases is a great mechanism to refine requirements, understand architecture, and ultimately demonstrate the value of fog to customers.
Actually, “use cases” is sort of an imprecise term, and I would like to propose a taxonomy that we can apply to more precisely understand how fog—and really any IoT capability—can be employed. This taxonomy has three levels: verticals, use cases, and applications.
