his Guidance helps you modernize your broker to gather, collect, and distribute data with your connected vehicle workloads using AWS IoT Core and Message Queuing Telemetry Transport (MQTT) 5. Most connected vehicle workloads require the vehicle to be connected to a cellular connection; otherwise, the vehicle would lack connectivity to receive commands from the cloud. With AWS IoT Core and the MQTT protocol, original equipment manufacturers (OEMs) can scale connected vehicles to meet demands during peak usage and right-size their workloads.
