Quickstart: Set up IoT Hub Device Provisioning Service with the Azure portal

  • Artikkeli

In this quickstart, you learn how to set up Azure IoT Hub Device Provisioning Service in the Azure portal. Device Provisioning Service enables zero-touch, just-in-time device provisioning to any IoT hub. The Device Provisioning Service enables customers to provision millions of IoT devices in a secure and scalable manner, without requiring human intervention. Azure IoT Hub Device Provisioning Service supports IoT devices with TPM, symmetric key, and X.509 certificate authentications.

Before you can provision your devices, you first perform the following steps:

  • Use the Azure portal to create an IoT hub
  • Use the Azure portal to create an IoT Hub Device Provisioning Service instance
  • Link the IoT hub to the Device Provisioning Service instance

Prerequisites

If you don't have an Azure subscription, create a free Azure account before you begin.
