This section describes how to create an IoT hub using the Azure portal.
Sign in to the Azure portal.
From the Azure homepage, select the + Create a resource button, and then enter IoT Hub in the Search the Marketplace field.
Select IoT Hub from the search results, and then select Create.
On the Basics tab, complete the fields as follows:
Subscription: Select the subscription to use for your hub.
Resource Group: Select a resource group or create a new one. To create a new one, select Create new and fill in the name you want to use. To use an existing resource group, select that resource group. For more information, see Manage Azure Resource Manager resource groups.
Region: Select the region in which you want your hub to be located. Select the location closest to you (e.g. UK West). Some features, such as IoT Hub device streams, are only available in specific regions. For these limited features, you must select one of the supported regions.
IoT Hub Name: Enter a name for your hub. This name must be globally unique.
Pricing and scale tier: Your selected tier. You can choose from several tiers, depending on how many features you want and how many messages you send through your solution per day. The free tier is intended for testing and evaluation. It allows 500 devices to be connected to the hub and up to 8,000 messages per day. Each Azure subscription can create one IoT hub in the free tier.
Important : Because the IoT hub will be publicly discoverable as a DNS endpoint, be sure to avoid entering any sensitive or personally identifiable information when you name it.
Select Next: Networking to continue creating your hub.
Choose the endpoints that can connect to your IoT Hub. You can select the default setting Public access.
Select Next: Management to continue creating your hub.
You can accept the default settings here. If desired, you can modify any of the following fields:
Scale > Device-to-cloud partitions: This property relates the device-to-cloud messages to the number of simultaneous readers of the messages. Most hubs need only four partitions.
Select Next: Add-ons to continue to the next screen. You can accept default settings here.
Select Next: Tags to continue to the next screen.
Tags are name/value pairs. You can assign the same tag to multiple resources and resource groups to categorize resources and consolidate billing. For more information, see Use tags to organize your Azure resources.
Select Next: Review + create to review your choices.
Select Create to create your new hub. Creating the hub takes a few minutes.
In the Azure portal, open your IoT hub. This should be available under Resource.
Click Devices under Device Management.
In the Devices pane, click Add to add a device to your IoT hub.
Device ID: The ID of the new device. Device IDs are case sensitive.
Authentication Type: Select Symmetric Key.
Auto Generate Keys: Check this field.
Connect device to IoT Hub: Click Enable.
Click Save.
After the device is created, open the device in the Devices pane. You may need to click the Refresh button for the device to appear.
Make a note of the primary key of the connection string, which looks like:
HostName={YourIoTHubName}.azure-devices.net;DeviceId=MyPythonDevice;SharedAccessKey={YourSharedAccessKey}
You'll use this value later in the next step.
