Let's take a look at how the Azure Active Directory, or Azure AD, identity model is able to effectively provide us with an Active Directory lite from the cloud. Azure AD may sound complex, but it isn't really. It's the default identity model for Office 365. So you may have already used it when creating users in Office 365. Imagine a database containing just a few user attributes, such as name, tenant, role, and password, all stored in the cloud using the highly available Azure Cloud Services that can scale to millions of records, an Active Directory lite, if you will, all without the layers and complexity that an on-premises Active Directory gives you.

There are no costs for using Azure Active Directory. There are, however, additional paid subscription levels for using the Azure Active Directory Basic and Premium tiers. These provide value-added features, such as company branding on the portal and user self-service password reset. To understand the Azure AD life cycle, let's first run through a typical scenario. A new user is created and then managed in Office 365.

The user account information is stored in Azure AD. And then whenever the user needs to be verified, all identity and access management is performed by Azure AD. This is always available, and it uses cloud-based Infrastructure as a Service, or IaaS. Azure AD allows you to move your Active Directory authentication services to the cloud. Whether these are public or private clouds, the data is always safe and available and stored in the data center.

If you want to retain local ownership, you can use Federation Services to provide on-premises identity whilst at the same time allowing you to extend your Active Directory environment to the cloud. We know that the cloud offers scalability and always-on availability. Because Azure AD is hosted in the cloud, it can be depended upon and accessed anywhere. Microsoft is able to expose Azure AD to other services via web-based protocols and application programming interfaces, or APIs, which allow trusted communications with Azure AD.

With these secure APIs, Azure AD can integrate with other services, such as on-premises AD, and allow the ability to have a single sign-on, or SSO, between separate services. Azure AD simplifies authentication by providing identity as a service. That is, Azure AD is responsible for verifying the identity of users. This can be achieved through a number of industry standard protocols, such as OAuth 2.0, SAML 2.0, OpenID Connect, and Web Services Federation, or WS-Federation.

When you use Office 365, Azure, or Intune, you are indirectly interfacing with Azure AD. There are also a number of tools to manage Azure AD. If you already have an Azure subscription, you can use the Azure portal if you only need to add or modify a few users. The Azure AD Connect tool, which replaces DirSync, is the primary synchronization tool and allows on-premises Active Directory accounts to be synced with Azure AD.

For more complex environments, you can manage on-premises resources with Active Directory Directory Services, or AD DS, with the Lightweight Directory Access Protocol, or LDAP. And Active Directory Federation Services, AD FS, can then be deployed on site, and this then provides single sign-on control locally. If you prefer working at the command line, you can also interact directly with Azure AD using the AD Graph API, which is a REST API, or by using the Azure AD PowerShell cmdlets, such as Get-AzureADUser and New-AzureADUser.
