Diverse Identities in Azure: Understanding the Key Components

Navigating identities within Azure can be quite a task, as it is a multifaceted journey that presents different and diverse identities and principles. However, it can be integral to managing access, security, and efficiency within the cloud environment. Azure Active Directory (Azure AD) works efficiently when it comes to overseeing diverse identity categories, ranging from user identities to service principals and managed identities.

To maximize the potential of Azure identities, one must grasp the full concept of key components. They are helpful in unleashing Azure’s identity management capabilities. Our discussion revolves around the intricacies of Azure AD and its role in managing user identities, service access, and device integration. Let’s unravel the complexities of Azure’s identity ecosystem in cloud services to understand how organizations can effectively leverage these tools to streamline operations and bolster security measures.

Diverse Identities in Azure

Azure AD oversees various identity categories:

  1. User Identity

User identity denotes entities managed within Azure AD, including employees and guests. Yet, for scenarios involving multiple users with identical access requirements, group creation proves beneficial. Rather than individually assigning access privileges, groups streamline the process by granting access permissions to all group members collectively.

  1. Service Principal

A service principal embodies a secure identity facilitating an application or service’s access to Azure resources. Conceptually, it serves as the application’s identity. However, prior to assuming its identity functions, an application necessitates registration with Microsoft Azure AD. Moreover, each tenant where the application operates hosts a distinct service principal, referencing the globally unique app object. The service principal delineates the application’s actions within the tenant, encompassing user access and resource accessibility.

  1. Managed Identity

Managed identities undergo automatic management within Azure AD. Primarily, they handle credential management for authenticating cloud applications with Azure services. Notably, employing managed identities offers several advantages:

  • Application developers can authenticate with services supporting managed identities for Azure resource manager.
  • Any Azure service backing Azure AD authentication can utilize managed identities to authenticate with another Azure service.
  • Importantly, no additional cost is incurred.

Types of Managed Identity

Managed identities manifest in two forms:

  1. System-assigned

Certain Azure services permit direct activation of a managed identity on a service instance. Upon activation, a system-assigned managed identity materializes in Azure AD, tethered to the lifecycle of the respective service instance. Subsequent to the removal of the resource, Azure autonomously eradicates the associated identity. Notably, solely the pertinent Azure resource can leverage this identity for Azure AD token requests.

  1. User-assigned

Alternatively, a managed identity can be independently created as a standalone Azure resource. A user-assigned managed identity is intended for one or more instances of an Azure service. By creating a user-assigned managed identity and assigning it to multiple Azure service instances, versatility and scalability are augmented.


Devices denote hardware entities, encompassing mobile devices, laptops, servers, and printers. Azure AD facilitates diverse methods for configuring device identities, influencing factors such as ownership attribution. Leveraging solutions like Microsoft Intune for device management within Azure AD empowers businesses to fortify assets while adhering to security and compliance standards. Various approaches exist for integrating devices into Azure AD:

  1. Azure AD Registered Devices

Spanning Windows 10, iOS, Android, or macOS devices, these devices are typically personally owned rather than organizationally provisioned.

  1. Azure AD Joined Devices

These devices exist solely in the cloud, are organization-owned, and are signed in with organizational accounts. Users access these devices using their Azure AD or synced Active Directory work or school accounts.

  1. Hybrid Azure AD Joined Devices

Encompassing Windows 7, 8.1, or 10, or Windows Server 2008 or newer, these devices are owned by the organization and sign in using Active Directory Domain Services accounts affiliated with the organization.


If you want to optimize and seek maximum potential from cloud operations, then you must master the intricacies of Azure’s identity management. By embracing and utilizing the capabilities of Azure Active Directory, businesses can effectively manage user access, secure service interactions, and seamlessly integrate devices into their ecosystem. Whether it’s about the use of user identities, service principals, or managed identities, Azure offers a complete package and framework for identity management. So, get started with Azure and enjoy a robust package for managing operations efficiently.
