Behold the ID scope, one of the most nuanced concepts in the IoT Hub Device Provisioning Service. It is both reviled and lauded for its name-spacing characteristics in device provisioning. It throws a wrench in complex provisioning scenarios, but it’s also necessary for secure zero-touch device provisioning.
This blog post is a culmination of several hours worth of conversations and design discussions in the engineering team, and it may take you several reads to fully understand. Understanding ID scopes is a journey, not a destination. If you don’t care about the details, just know that ID scopes are necessary to ensure identity uniqueness in the device supply chain. If you want to know why, read on.
