Azure Active Directory is Microsoft’s cloud-based identity and access management service. With Azure AD, IT administrators can manage users and groups, providing secure access to applications both in the cloud and on-premises. Azure AD integrates with many SaaS applications and offers features such as:
An example of how Azure AD can be used is to provide employees with access to Office 365, Salesforce, and other third-party SaaS applications using SSO. With Conditional Access, employees accessing corporate resources from an external network may be required to complete MFA, enhancing security.
Azure Active Directory Domain Services is a more specialized service providing managed domain services like domain join, group policy, LDAP, Kerberos/NTLM authentication that are fully compatible with Windows Server Active Directory. Azure AD DS is beneficial for organizations that want to lift and shift applications to Azure that depend on traditional on-premises domain services without the need to manage a complete domain controller infrastructure in the cloud.
Features of Azure AD DS include:
A typical use case for Azure AD DS could involve running an application on Azure that requires LDAP binding or Windows Integrated Authentication without needing to deploy and manage full domain controllers.
Feature | Azure AD | Azure AD DS |
---|---|---|
Sign-on protocol support | SAML, OAuth, OpenID Connect | LDAP, Kerberos, NTLM |
Integration with on-premises AD | Azure AD Connect | Direct synchronization with Azure AD |
Management overhead | Low (fully managed service) | Low (fully managed domain services) |
Suitable for SaaS applications | Yes | No (designed for legacy applications) |
Group policy | No | Yes |
Traditional domain join | No | Yes |
Cost | Free tier available, pay-for-use premium tiers | Pay-for-use based on resource usage |
Use case | Modern cloud applications, Office 365 | Legacy applications requiring Windows AD features |
Azure Active Directory and Azure Active Directory Domain Services provide comprehensive directory and identity services suitable for different enterprise needs. Azure AD is ideal for managing cloud-based s applications, supporting modern authentication protocols, and reducing management overhead. Azure AD DS, on the other hand, is tailored for traditional on-premises applications that rely on Windows AD features and require minimal changes to migrate to Azure. Understanding the differences and use cases of these services is crucial for effectively managing identity and access within the Azure ecosystem.
Azure AD is Microsoft’s cloud-based identity and access management service, helping organizations manage user identities and create intelligence-driven access policies.
Answer: A, B, C

Azure AD DS can be integrated with an on-premises Active Directory to provide a consistent identity for users.
Answer: A, B, C
Azure AD supports Password Hash Synchronization, smart cards, and OAuth 0 as authentication methods, but does not support SQL Authentication, which is for databases.
Multi-Factor Authentication is a feature available in Azure AD to enhance security.
Answer: B
Azure AD DS is not enabled by default; it needs to be set up separately from the Azure AD instance.
Answer: B
Azure AD Application Proxy helps manage and secure access to internal applications without opening broad access to the network.
Azure AD B2C is meant for building customer identity and access management in the cloud for consumer-facing applications.
Answer: A
Azure AD Connect is used to synchronize an on-premises Active Directory with Azure AD, allowing for a hybrid identity solution.
Azure AD DS works over the internet and does not require a VPN for operation with on-premises environments, although a VPN or ExpressRoute can be used for enhanced security and reliability.
Azure AD is a cloud-based identity and access management service that helps manage and secure user access to various applications and services.
Azure AD DS provides domain services such as domain join, group policy, LDAP, and Kerberos/NTLM authentication that are fully compatible with Windows Server Active Directory.
Azure AD is a cloud-based identity and access management service that provides access to cloud-based applications and resources, while Azure AD DS is a managed domain service that provides domain services such as domain join, group policy, LDAP, and Kerberos/NTLM authentication.
Azure AD provides a centralized identity management solution that simplifies user and group management and provides a single sign-on experience for users across multiple applications and services.
Azure AD DS allows organizations to use familiar tools and processes to manage domain-joined resources in the cloud, enabling organizations to move their legacy applications to the cloud without the need for extensive re-architecture.
Azure AD provides features such as single sign-on, multi-factor authentication, conditional access, and self-service password reset.
SSO is a feature that allows users to authenticate once and then access multiple applications and services without having to re-enter their credentials.
MFA is a security feature that requires users to provide two or more forms of authentication to access an application or service.
Conditional access is a feature that allows organizations to control access to applications and resources based on various conditions such as device compliance, user location, and risk level.
Self-service password reset is a feature that allows users to reset their passwords without the need for IT assistance, which helps reduce the workload on IT staff.
Azure AD Connect is a tool that enables organizations to synchronize their on-premises directories with Azure AD, providing a single identity for users across both on-premises and cloud-based applications and services.
Azure AD B2C is a cloud-based identity and access management service that provides a scalable solution for consumer-facing applications, allowing organizations to manage customer identities and access to applications and services.
Azure AD Domain Services managed domain is an Azure-managed domain that provides compatibility with on-premises Active Directory, allowing organizations to use their existing Group Policy and domain-joined devices in the cloud.
An Azure AD Tenant is a dedicated instance of Azure AD that represents an organization, and provides a single identity for users across various applications and services.
Azure AD Identity Protection is a security feature that helps protect against identity-based attacks by providing threat detection, risk assessment, and remediation recommendations.
