How to register your Azure resource as an Application in Azure Active Directory?

Question

I have an Azure CDN. It has a custom domain, and I attempting to register my own certificate for HTTPS support.

I am attempting to follow the instructions here: https://docs.microsoft.com/en-us/azure/cdn/cdn-custom-ssl?tabs=option-2-enable-https-with-your-own-certificate

I have uploaded my Certificate to a Key Vault. That should be good. I am now trying grant my Azure CDN Profile access to my Key Vault in order for it to get the certificate. That is this step in the tutorial (Register Azure CDN, step #2)

That step shows a GUID (205478c0-bd83-4e1b-a9d6-db63a3e1e1c8). Where is that coming from? Is that the identifier for my Azure CDN Profile? If so, where would I get that?

I also just noticed there are two commands there: The text shows New-AzADServicePrincipal, but the screenshot shows New-AzureRmADServicePrincipal. Presumably, the latter is the (older?) command based on Resource Manager. But, which one should I be using?

Also, I don't think I have Azure Powershell installed. Can I do this using Cloud Shell via the Azure Portal?

What I see when I attempt to run the command from Cloud Shell

That step shows a GUID (205478c0-bd83-4e1b-a9d6-db63a3e1e1c8). Where is that coming from? Is that the identifier for my Azure CDN Profile? If so, where would I get that?

The GUID is the Application ID of the multi-tenant AD App in the Microsoft tenant( microsoft.onmicrosoft.com ), when you use the New-AzADServicePrincipal with the GUID, it will create a service principal related to this AD App in your AAD tenant, which represents your CDN.

When you run the New-AzADServicePrincipal successfully, you could find it in the portal -> Azure Active Directory -> Enterprise applications in your tenant.

I also just noticed there are two commands there: The text shows New-AzADServicePrincipal, but the screenshot shows New-AzureRmADServicePrincipal. Presumably, the latter is the (older?) command based on Resource Manager. But, which one should I be using?

The New-AzureRmADServicePrincipal belongs to the old AzureRM module, New-AzADServicePrincipal belongs to the new Az module. You could use both of them, but I recommend you to use New-AzADServicePrincipal , because the AzureRM module was deprecated and will not be updated any more.

Also, I don't think I have Azure Powershell installed. Can I do this using Cloud Shell via the Azure Portal?

Of course, you can. Just run that in the cloud shell, no need to install any module manually.
