A Microservice Architecture for Multimobility in a Smart City

In this paper we present a microservice architecture designed to build IoT services available on the Web. The high potential of microservice architectures will impact the design of complex systems more significantly in the coming years. We propose a draft of architecture that we have used to develop an application for multimobility services in a smart city using an ecosystem of devices. Such application, designed for a real case study, is extremely heterogeneous in terms of IoT devices and implements a wide range of services for citizens. It aims to give a contribution to reducing traffic generated by private vehicles in the city and to help drivers going towards high traffic areas by presenting real-time mobility data from different sources. The evaluation of the architecture carried out in this study allows to understand how it behaves under an increasing number of devices and users connected to the platform, particularly in terms of response time alterations caused by a large number of requests.
