An Azure Active Directory (AAD) Instance is a specific implementation of Azure Active Directory, representing a unique directory within the Azure cloud environment.
- Context:
- It can (typically) contains identities, credentials, and policies that are managed within the Azure ecosystem, allowing for the control of access to resources and services.
- It can (typically) be identified by a Azure Directory Name, which is chosen during the creation of the instance and is used to label the directory within the Azure portal.
- It can (often) be associated with a Azure Domain Name, usually in the format of yourdomain.onmicrosoft.com, which is automatically generated when the directory is created and can be used for email addresses and login IDs.
- ...
- It can include a unique Directory ID (a GUID), which is used internally by Azure and other services to identify and reference the specific directory uniquely.
- It can be marked as the Default Directory for an Azure subscription, meaning it is the primary directory that is interacted with when accessing Azure services.
- It can indicate the Current Directory being used in an Azure session, which helps users identify which directory they are actively working within if they have access to multiple directories.
- It can be associated with a Default Domain, such as gabormelligmail.onmicrosoft.com, the initial domain Azure assigned during directory setup and often used for initial administrative tasks.
- It can manage identities, permissions, and services within the Azure cloud, serving as the backbone for identity and access management in the cloud environment.
- It can be linked to various Azure services and applications, allowing them to authenticate and authorize users through the identity data stored within the AAD instance.
- It can be customized with custom domain names, allowing organizations to use their branded domains instead of the default onmicrosoft.com domain.

- Example(s):
- One with Azure Directory ID "21e0281f-13e7-....-a30c-aaa2e94a73e9"
- One used by an enterprise to uniquely identify and manage its AAD instance, supporting a large-scale cloud migration.
- ...
- Counter-Example(s):
- A Local Active Directory Domain that operates within an on-premises network and does not provide cloud-based identity and access management.
- A Workgroup environment that does not use a centralized directory service for managing user identities and permissions.
