IoT Hub limits

According to the documentation for IoT hub quotas and throttling it looks lika an IoT hub only allowes a total of 300mb for device streaming. This is per hub and not per device. Is this correctly understood? So a hub that allowes 1 miljon devices should share 300mb.

    Hello @Mikael Wilfeldt.

    welcome to this moderated Azure community forum.

    You are referencing the Azure IoT Hub device stream:

    This is a special ability of the IoT Hub which is in preview and is expected not to become GA.

    This is because the IoT hub is considered feature complete.

    I recommend looking for another ways to transfer device data as a stream.

    Just for completion, if you are interested in the message throughput, check the operations limit for device to cloud communication:

    An operation is a call from a device. A call ban be 4KB to 256KB in size.

    This is per IoT Hub as documented.
