What is the default allocation policy for Azure IoT DPS systems?

The default allocation policy for Azure IoT Device Provisioning Service (DPS) systems is the evenly weighted distribution method. This policy is designed to distribute devices across the available IoT Hub instances in a balanced manner. By using an evenly weighted distribution, Azure IoT DPS ensures that the load is shared equally among all the configured IoT Hubs, which helps in managing resources effectively and prevents any single IoT Hub from becoming overwhelmed with traffic.

This policy is particularly important in scenarios where multiple IoT Hubs are utilized to support the provisioning of devices at scale, ensuring that all Hubs are utilized efficiently and that there is resilience in the provisioning process. By avoiding both overloading a single Hub and underutilizing others, Azure IoT DPS provides a more robust and reliable provisioning experience for device connections.
