Azure Mobile Services
This example is currently being developed.
By utilising Azure Mobile Services, Stream Anaytics, Event Hubs and potentially Machine Learning. It is possible to notify someone or a large group of people when particular triggers occur.
For example, telemetry data that is being ingested by Event Hub from many thousands (or even millions) of devices, could have the data aggregated by geography and this aggregated data could then query a Machine Leanring Model to provide predictions related to weather, traffic etc. This information could then be sent to drivers so as to avoid a particular area or to famers to notify them of potential harsh localised weather conditions.
Another example would be to aggregate on an individual sensor system, in which predictions of whether a particular system needs maintainence could be made. This prediction could then be messaged to maintainence crew, enabling them to priorities their schedule for greatest effeciency.
