如何将O365订阅与Azure AD订阅相关联

有人可以帮我解决以下问题。

Can someone please help me with the following question.

我正在读一本关于Azure和0365的书

I am reading a book about Azure and 0365

这本书说首先设置0365 Enterprise E5的跟踪版本，这样我就可以学习并完成本书中的实践（有意义）。我成功完成了这项工作，现在有一个< MyDomain> .onmicrosoft.com 域名和电子邮件登录。 

The book says first of all setup a trail version of 0365 Enterprise E5, so I can learn and do the practices in the book (makes sense). I did this successfully and now have an <MyDomain>.onmicrosoft.com  domain and email logon. 

本书旁边说我应该设置Azure AD订阅，因为我需要执行"Azure AD域服务"等操作来完成一些实践本书后面。

Next to book says I should setup a subscription to Azure AD as I will need to do things like 'Azure AD Domain Services' to complete some of the practices later in the book.

Hers就是这样，

我知道0365由Azure AD支持，因此如果我在0365中创建用户管理员门户网站，我实际上是在Azure AD租户中创建用户，例如  < MyDomain> .onmicrosoft.com

I know 0365 is backed by Azure AD, therefore if I create a user in the 0365 admin portal, I am actually creating a user in Azure AD tenant e.g.  <MyDomain>.onmicrosoft.com

我也意识到O365订阅不会为您提供IaaS功能等（因为它以SaaS为中心。） 

I also realise an O365 subscription does not give you IaaS capabilities etc (as it is centred around SaaS). 

所以我可以看到为什么这本书可能会说我还需要设置一个Azure AD租户，但我不能用户 < MyDomain>设置Azure AD租户时.onmicrosoft.com，因为我的O365订阅已经采用了这种方式 

So I can see why the book might say I need to also setup an Azure AD tenant, however I cannot user <MyDomain>.onmicrosoft.com when setting up the Azure AD tenant as this is already taken by my O365 subscription 

我可以创建< MyDomain2> .onmicrosoft.com Azure AD租户但是，这个似乎没有多大意义，因为这个租户中的任何用户都会与我的O3分开65租客 

I could create <MyDomain2>.onmicrosoft.com Azure AD tenant but, this would not appear to make much sense as any users in this tenant would be separate from my O365 tenant 

所以我对最好的事情感到困惑，因为这本书没有说清楚/

So I am a bit confused about the best thing to do as the book does not make it clear/

有没有办法在设置Azure AD租户以使用我的O365管理员登录时，其中会自动将新的Azure AD租户（用于Iaas和Paas之类的东西）与我当前的O365租户关联？

Is there a way when setting up an Azure AD tenant to use my O365 admin logon, and therein automatically associate a new Azure AD tenant (to be used for things like Iaas and Paas) to my current O365 tenant ?

如果不是，我想我将不得不邀请我的O365用户到我的新Azure AD租户使用我的Azure AD租户中的任何服务？

If not I guess I will have to invite my O365 users to my new Azure AD tenant to use any services in my Azure AD tenant ?

请帮助

谢谢
