Understanding Azure Active Directory
Azure Active Directory (Azure AD) is key for companies using cloud services. It grew from Microsoft’s Active Directory, focusing on cloud features through Microsoft Entra ID. Unlike old systems, Azure AD manages identities across many platforms and works well with different apps.
An Azure AD overview shows important parts. Companies with Microsoft Online services, like Office 365, get Azure AD automatically. This lets them create cloud-only accounts for B2B and B2C interactions. It makes it easy to access services without needing old Active Directory setups.
- Three main user types interact with Azure Active Directory:
- IT administrators who set up users, groups, and permissions.
- Application developers who use APIs with Azure AD credentials in their apps.
- Business users who log into cloud resources, often not knowing about Azure AD.
Azure AD has different licensing levels. Some features are free, but better security needs a Basic or higher license. It supports many ways to log in, making it safer and easier for remote workers.
Azure AD uses a flat structure called a “tenant,” unlike Windows Active Directory’s hierarchy. Knowing Azure Active Directory is vital for managing today’s hybrid IT environments. It ensures smooth identity management, boosting efficiency and security.
What are the types of Azure AD?
Knowing the types of Azure AD is key for companies using Microsoft’s cloud services. There are several Azure AD types, each for different needs. These include Azure Active Directory (AAD), Hybrid Azure Active Directory (Hybrid AAD), and Azure Active Directory Domain Services (AAD DS). Also, Azure AD B2C and Azure AD B2B cater to specific business models.
Azure AD types vary by features and functions. For example, security groups can come from Azure AD or be synced with on-premises Active Directory. Microsoft 365 groups are also important, working with apps like Microsoft Teams for a smooth user experience.
Another important part of Azure AD is the devices it supports for identity management. Companies can use Azure AD-registered, Azure AD-joined, or Hybrid Azure AD-joined devices. This flexibility is great for both company and BYOD setups.
Knowing these differences helps companies pick the right Azure AD version for their needs. This ensures good user identity management and security.
Azure Active Directory (AAD)
Azure Active Directory is a key cloud identity platform for today’s businesses. It helps manage who can access what and where. It works with Windows, Apple, and Linux, making identity management easy across different platforms.

Azure Active Directory Domain Services (AAD DS)
Azure Active Directory Domain Services (AAD DS) offers key managed domain features without the need for traditional domain controllers. It lets organizations sync users, groups, and credentials easily from Azure AD. This makes accessing on-premises resources in Azure more efficient.
AAD DS supports Kerberos and NTLM authentication, as well as LDAP queries. It’s a key tool for managing identity and authentication in the cloud.
When setting up Azure AD DS, picking a namespace that matches the organization’s domain name is important. At least two Windows Server domain controllers are needed for redundancy. If one fails, the other takes over, ensuring service continuity.
AAD DS automatically handles backups and data encryption with Azure Disk Encryption. It synchronizes one-way from Azure AD to the managed domain. But, resources created in the managed domain don’t sync back to Azure AD.
The features of Azure AD DS work the same whether in the cloud or synced with on-premises Active Directory Domain Services.
- Extension of managed domains across multiple replica sets for geo-disaster recovery.
- Support for group policies to streamline device and user management.
- Redundant availability with at least two domain controllers to ensure service continuity.
- Integration with Azure AD enables seamless authentication across applications.
Azure AD DS doesn’t fully replace traditional Active Directory. It lacks domain trusts and certain admin rights. Management is through the “AAD DC Administrators” group, not standard domain admin accounts.
Organizations moving to Azure AD DS need to consider these limitations. This is important if they use legacy apps that can’t use modern authentication.
Azure AD B2C: Business to Consumer
Azure AD B2C is key in managing customer identities. It helps businesses manage identities well and gives users a smooth experience. Companies can make sign-up and sign-in processes their own, using names, emails, and phone numbers.
