How Azure for Active Directory Works: The Architecture Explained
To fully appreciate Azure for Active Directory, it’s essential to understand its underlying architecture. Unlike traditional AD, which is hierarchical and domain-based, Azure AD is a flat, REST-based directory service optimized for web-scale applications.
Global Tenant Model and Multi-Tenancy
Azure for Active Directory operates on a tenant-based model. Each organization has its own isolated tenant—a dedicated instance of Azure AD that contains its users, groups, and policies.
- Tenants are identified by a unique domain (e.g., contoso.onmicrosoft.com).
- Supports multi-geo deployments for global organizations.
- Enables cross-tenant access for partnerships and mergers.
This model ensures data isolation while allowing secure collaboration across organizational boundaries.
Authentication Flow and Token-Based Access
Azure for Active Directory uses modern authentication protocols that replace passwords with secure tokens.
- When a user logs in, Azure AD validates credentials and issues a JSON Web Token (JWT).
- The token contains claims about the user’s identity and permissions.
- Applications validate the token to grant access without storing passwords.
This approach minimizes the risk of credential theft and supports federated identity scenarios.
Hybrid Identity with Azure AD Connect
For organizations not ready to go fully cloud-native, Azure for Active Directory offers hybrid identity solutions through Azure AD Connect.
- Synchronizes user accounts from on-premises AD to Azure AD.
- Supports password hash synchronization, pass-through authentication, and federation.
- Enables seamless user experience with SSO and MFA.
Microsoft recommends pass-through authentication for most hybrid scenarios due to its simplicity and security. More details are available at Azure AD hybrid identity documentation.
