An Azure service that enables bidirectional communication between internet of things (IoT) devices and applications.
Azure for Students subscriptions are restricted to specific deployment regions, and the allowed list varies by subscription. The regions shown in the Allowed locations policy are the regions that can be used for deployments.
For an IoT Hub deployment, first verify the allowed regions in Azure portal:
- Go to Azure Policy → Assignments.
- Open Allowed resource deployment regions or a similarly named assignment.
- Check the allowedLocations parameter value.
- Try creating the IoT Hub in one of those exact regions.
When creating the IoT Hub in the portal:
- Select + Create a resource.
- Go to Internet of Things → IoT Hub.
- On Basics, set the hub name, subscription, resource group, and choose one of the allowed regions.
- Continue through Networking, Management, and Review + create.
If deployment still fails even when using one of the regions already allowed by policy, the documented path is to submit a support request in Azure portal for region access remediation. Microsoft guidance says this should be done when there is a clear business need or when region access needs to be reviewed.
If the issue is specifically that the portal does not offer a usable region even though policy allows regions, most users should either:
- select a different allowed region, or
- submit a support request for region access review
Also note that some services can fail in a region because of service availability, capacity, quota, or policy restrictions, even if a region appears as an option.
