The automotive industry is embracing the idea of building a connected car. They see opportunity in using telemetry data from vehicles to create new revenue opportunities, and to build a better user experience. However, implementing a connected car service that can scale to support millions of cars can present some challenges.
For most connected car services, there is a requirement for bi-directional communication between the car and the cloud. Cars will send telemetry data to the cloud and enable apps like predictive maintenance, assisted driving, etc. Similarly, the car needs to be able to receive messages from the cloud to respond to remote commands, like remote lock/unlock door and remote activation of horn or lights.
