A view model of API economy in city platform as a service

Computer and communication technologies are leveraging IoT, the Internet of Things. The radical digital transformation empowered by IoT has paved the way of innovating service engineering in the context of cyber-physical space. There is a wide range of opportunities of the API economy using IoT. However, a systematic methodology to assist service engineering in the scope of the API economy is still underexplored. The author presents a view model of the API economy to facilitate API development in a smart city platform. Then, the author discusses transition paths to deal with chasms between different layers of the API economy. Finally, the author discusses the scalability view of APIs.
