Azure Subscription VS Microsoft 365 (Office 365) Subscription
Azure订阅VS Microsoft 365（Office 365）订阅

Microsoft Online business services, such as Microsoft 365 or Microsoft Azure, require Azure AD for sign-in activities and to help with identity protection. If you subscribe to any Microsoft Online business service, you automatically get Azure AD with access to all the free features.
Microsoft Online业务服务（如Microsoft 365或Microsoft Azure）需要Azure AD进行登录活动并帮助进行身份保护。如果您订阅了任何Microsoft Online业务服务，您将自动获得Azure AD，并可以访问所有免费功能。
When a user signs up for a Microsoft cloud service, a new Azure AD tenant is created and the user is made a member of the Global Administrator role. 
当用户注册Microsoft云服务时，将创建一个新的Azure AD租户，并且用户将成为全局管理员角色的成员。
All of your users have a single home directory for authentication. Your users can also be guests in other directories. You can see both the home and guest directories for each user in Azure AD.
所有用户都有一个用于身份验证的主目录。您的用户也可以是其他目录中的来宾。您可以在Azure AD中看到每个用户的主目录和来宾目录。
 

Microsoft 365 and Azure use the Azure AD service to manage users and subscriptions. The Azure directory is like a container in which you can group users and subscriptions. To use the same user accounts for your Azure and Microsoft 365 subscriptions, you need to make sure that the Azure subscriptions are created in the same directory as the Microsoft 365 subscriptions. Keep in mind the following points:
Microsoft 365和Azure使用Azure AD服务来管理用户和订阅。Azure目录就像一个容器，您可以在其中对用户和订阅进行分组。要为Azure和Microsoft 365订阅使用相同的用户帐户，您需要确保Azure订阅与Microsoft 365订阅在同一目录中创建。请记住以下几点：

  • A subscription gets created under a directory
    在目录下创建订阅
  • Users belong to directories
    用户属于目录
  • A subscription lands in the directory of the user who creates the subscription. So your Microsoft 365 subscription is tied to the same account as your Azure subscription.
    订阅位于创建订阅的用户的目录中。因此，您的Microsoft 365订阅与您的Azure订阅绑定到同一帐户。
  • Azure subscriptions are owned by individual users in the directory
    Azure订阅由目录中的单个用户拥有
  • Microsoft 365 subscriptions are owned by the directory itself. Users with the right permissions within the directory can manage these subscriptions.
    Microsoft 365订阅归目录本身所有。在目录中具有正确权限的用户可以管理这些订阅。

Screenshot that shows the relationship of the directory, users, and subscriptions.

 
If you’re Azure subscriber, you can use your Azure account to sign up for a Microsoft 365 subscription. If you’re part of an organization that has an Azure subscription, you can create Microsoft 365 subscriptions for users in your existing Azure Active Directory (Azure AD). Sign up for Microsoft 365 using an account that has Global Admin or Billing Admin permissions in your Azure Active Directory tenant.
如果您是Azure订阅者，则可以使用Azure帐户注册Microsoft 365订阅。如果您属于拥有Azure订阅的组织，则可以为现有Azure Active Directory（Azure AD）中的用户创建Microsoft 365订阅。使用在Azure Active Directory租户中具有全局管理员或计费管理员权限的帐户注册Microsoft 365。
