9. Device provisioning Making devices known to your system
Microsoft Ignite 2015
2/23/2019 4:17 AM
Device provisioning
Making devices known to your system
Many systems involved (IoT Hub, device registry, ERPs, …)
Device identity (composite devices, many concerns)
Sample provisioning
Device provisioned at manufacturing into system
Device connects for the first time and gets associated to its regional data center (bootstrapped)
As a result of customer interactions the device is activated
Devices can be deactivated for security and other reasons
A device can also be de-provisioned at end-of-life or decommission.
Provisioned
Bootstrapped
Activated
Deactivated
De-provisioned
