Today we're announcing the public preview of the Azure IoT Hub Device Provisioning Service! The Device Provisioning Service is new service that works with Azure IoT Hub to enable customers to configure zero-touch device provisioning to their IoT hub. With the Device Provisioning Service, you can provision millions of devices in a secure and scalable manner, automating a process that has historically been time and resource intensive for manufacturers and companies managing volumes of connected devices. The Device Provisioning Service is the only cloud service to provide complete automated provisioning, including both registering the device to the cloud as well as configuring the device. Device Provisioning Service is available in East US, West Europe, and Southeast Asia starting today, and eventually will be available globally.
Without a provisioning service, connecting devices to Azure IoT Hub requires manual work. Each device needs a unique identity to enable per-device access revocation in case the device is compromised. Doing this manually works for very few devices, but at IoT scale, you have to individually place connection credentials on each of millions of devices.
