Since request made by these Alexa devices will be communicating with the Nissan Middleware and the 3 rd party services which are in already in place, there is need to introduce an intermediate middleware. IoT middleware will be acting as a web channel / gateway / intermediate middleware in order to facilitate these service requests. Based on the requests and responses, IoT middleware is benefit the business in terms of analytics, metering, routing, auditing, orchestration which will eventually result in monetization.
