As companies continue to fully roll out their IoT projects, management of the various components of the solution becomes a critical part of their operations. The flexibility of Azure IoT Hub to enable customers to start small, paying only for the amount of IoT Hub capacity needed at any point along the device deployment curve, helps drive predictability in the cost of an IoT solution.
However, the potentially irregular rate of device and message growth in an IoT solution does add a unique challenge for operations. When the number of messages ingested from devices in a given day exceeds the limit of the chosen IoT Hub capacity, the IoT Hub will begin to reject messages until either the IoT Hub is scaled-up, or the time rolls over into the next day (UTC time). Wouldn’t it be nice to have IoT Hub just automatically scale up to a higher capacity when a certain threshold of messages is met, before this limit is reached?
