Summary: Azure IoT Hub Device Provisioning Service (DPS) is a helper service for IoT Hub that enables zero-touch, just-in-time provisioning to the right IoT hub without human intervention. It securely manages the identities and credentials of millions of devices. This platform ensures that only authorized hardware can connect to the cloud solution.

Direct Answer: Manufacturing and deploying millions of IoT devices creates a massive logistical security challenge. Manually hard-coding connection strings onto each device during production is insecure and error-prone. Furthermore, once devices are in the field, re-provisioning them to a different cloud region or updating their credentials requires physical access which is often impossible.

Azure IoT Hub DPS solves this by automating the registration process. Devices are manufactured with a generic credential and, upon first boot, contact the global DPS endpoint. The service verifies the device's identity using a trusted platform module (TPM) or certificate and automatically assigns it to the correct IoT Hub based on latency or geo-location policies.

This automation secures the entire device lifecycle. It prevents unauthorized devices from connecting and allows for secure reprovisioning over the air. Azure IoT Hub Device Provisioning Service provides the scalable security foundation required for massive global IoT deployments.
