What is the Azure active directory and how Azure AD works?

First, Let’s discuss What is the Azure active directory and then we will discuss how Azure AD works?

What is Azure Active Directory

In simple words, Azure Active Directory is the cloud version of Active Directory.

It also is popularly known as Azure AD, which is the single and universal cloud-based identity and access management platform. Every organization will have an Azure AD or AD which helps employees to sign in and access various resources within the organization.

Azure AD is the identity platform to manage your internal and external users securely. Organizations use Azure AD to store user information like Name, ID, Email, Address, etc.

According to Microsoft Every day, Azure AD manages more than 1.2 billion identities and processes over 8 billion authentications which is huge in numbers.

Few days to day activities that usually happen in an Azure AD are like:

  • Add or delete users
  • Restore users
  • Add or change user profile information
  • Reset or Change a user’s password
  • Self-service password reset
  • Assign or remove user roles
  • Assign or remove user licenses
  • Create or delete Azure AD groups
  • Edit Azure AD group information
  • Add or remove members from Azure AD groups
  • Add, remove or change Azure AD group owners, etc.

Azure Active Directory supports single sign-on to more than 2800 SaaS (software as a service) applications like Azure, Office 365, salesforce, Google Apps, ServiceNow, etc. Through single sign-on, users can enter credentials once and then can access other applications or services without entering any credentials.

Azure AD also provides identity management for PaaS and IaaS applications.

What is the difference between Active Directory and Azure Active Directory?

Now let us see what is the difference between AD and Azure AD.

Active Directory (AD) is like a database that is used to store an organization’s users, groups and computers, etc. AD also provides authentication and authorization to various applications, file servers, printers, and various other resources inside the organization.

Windows AD comes with Windows server editions. First, AD comes with windows server 2000.

On the other side, Azure AD is the cloud version of AD. Azure AD exists in Microsoft data centers that store information about users, groups, etc. If you are having an Office 365 subscription, then you have by default Azure AD.

One of the major differences between AD and Azure AD, AD is designed for Windows applications or on-premises applications. On the other hand, Azure AD is designed for web-based services. Azure AD supports various web-based services like Salesforce, Office 365, Azure, etc.

In Windows Active Directory, we create forests and domains. But in Azure AD, you will create a tenant for the entire organization.

Can Azure AD replace Active Directory?

This question comes can Azure AD replace AD? Azure AD is not a replacement for Windows AD.

If organizations have on-premises AD, then you can integrate on-premises AD with Azure AD Connect which will sync AD and Azure AD. After that, the user authenticates using the same credentials.

Suppose, you do not have an on-premises Windows AD, then you can have an Office 365 subscription where you can access Azure AD with other various online services.

Does Office 365 require Azure AD?

Does Office 365 require Azure AD? Yes, it requires.

Behind the scenes, Office 365 uses Azure Active Directory or Azure AD. Office 365 manages users inside Azure AD, which is a free subscription to Azure AD which comes with Office 365 subscription.

As an Office 365 subscription user, you can access Office 365 apps like mail, calendar, contacts, users, groups, fields, etc. with single sign-on.
