Multi tenancy in Powerbi Service

Hi Anonymous 

thanks for the reply.

Regarding the powerbi service parameters i got it and it could be a solution for part of my problem.

Now, each client has their own database where they are running their businesses. I cannot expose these reports to "public". 

In general terms i want/need to control the users that have access to a report. If i have to create several copies of the same report, each one poiting to the client database, that would be acceptable. 

I was just trying to understand if someone already created this type of approach, if it's manageable and how to control the accounts and the access.

I have clients that don't have any kind of relationship with Microsoft and being so, what is the best approach for this kind of user when it comes to powerbi?

Should i create them in our AD as guests and "give" them a powerbi account on out tenant? Or should they create a powerbi account and i just share the reports with them?

Would it be better to use one tenant that i control or should i tell my clients that they need to create a tenant and then i step in and install the reports?

Thanks
