Join a Computer to Azure Active Directory
As more companies use or migrate to the cloud to provide services, Windows Active Directory can also be used this way. In the Microsoft Cloud, Windows Active Directory becomes Azure Active Directory. Small to medium size businesses (SMBs) might choose to not have on-premise servers (including Domain Controllers). An inexpensive way to leverage Active Directory is by using it in Azure.
A company must have Office 365 before you can use Azure Active Directory.
