If your cloud resources are in an Azure cloud, you must create a user identity
called a service principal that grants permissions to the MID Server to access selected
resources.

## Azure management groups and subscriptions {#azure-cloud-discovery__section_zsr_zbb_kmb}

An Azure management group contains other management groups and subscriptions. The management groups in an Azure Cloud environment form a hierarchy, but
don't contain volumes or virtual
machines. Subscriptions contain cloud resources, such as virtual machines. The subscriptions that belong to management groups are called sub-accounts.

The advantages of using management groups are:

Easy population of sub-accounts

After you configure the management group and supply the necessary credentials, you can test the account. If the test succeeds, Discovery returns a list of subscriptions in that management group. From this list, you can choose
one or more subscription sub-accounts to include in the Discovery schedule using the management group. For more information on
the hierarchy of management groups and subscriptions, see [Organize your resources with Azure management groups](https://docs.microsoft.com/en-us/azure/governance/management-groups/overview)

Discovery of sub-account resources using dynamically acquired credentials

When you run Discovery on your subscriptions, you do not need separate credentials for each sub-account. Discovery finds the credentials for the management group and maps them to all of the subscription sub-accounts. The Cloud
Discovery process handles credentials automatically by acquiring a temporary credential for each sub-account via an Azure API. You can elect to use the default configuration or customize the MID Server to assume other roles for
additional controls and security. In addition, Discovery can automatically refresh the list of sub-accounts and datacenters
covered in a discovery schedule. For more information, see the KB article [Retrieve newer accounts/sub-accounts automatically via Cloud Discovery.](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0961449)
A service principal for Azure cloud services is similar to a Microsoft
Windows service account that enables Windows processes to
communicate with each other within an Active Directory domain.  
To create the Azure service principal in your ServiceNow instance, copy the service principal credential values from the Azure portal into a text editor, and then transfer those values into the instance. Figure 1. The text file that you generate during this procedure  
This table shows you the Azure Service Principal value and the location in Azure where you can find the values you need for the credentials.{#azure-cloud-discovery__table_kpc_svh_wjb__entry__3}

| Cloud Provisioning and Governance setting | Azure Service Principal value | Location of the Azure value |

## Verify the REST API Permissions {#azure-cloud-discovery__id_ppz_r33_ydc}

Download the [Cloud Discovery patterns spreadsheet](https://downloads.docs.servicenow.com/resource/enus/api/servicenow-discovery-patterns-api-details.xlsx) so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available
quarterly, so check periodically to be sure you have the latest version of the spreadsheet.{#azure-cloud-discovery__cloud-discovery-api-paragraph}

## Data collected by Service Mapping during top-down discovery {#azure-cloud-discovery__section_mtq_nbg_ppb}

To include discovered components into application services, enable CI relationships used in tag-based discovery by Service Mapping. These CI relationships are available from the 1.0.68 release on the ServiceNow Store. For operational steps, see [Tag-based discovery configuration](https://www.servicenow.com/docs/1S9E9aQ6o6GYkFbPv2A1Hg "You can refine the default configuration to control which CIs Service Mapping includes in application services during the tag-based discovery process.").  
Service Mapping uses tag-based discovery to create service instance maps including the Cloud components. The Service Mapping application comes with the following preconfigured CI relationships used for tag-based discovery. These CI relationships are available from the 1.0.68 release on the ServiceNow Store. {#azure-cloud-discovery__id_yqp_xhy_qpb__entry__3}
