Report server access

Hello

I have installed Power BI Report Server on VM Using Azure but i have few questions regarding access to it. 

1.   http://servername//reports/ - Should be visible outside the VM machine. How? And like if using sharepoint, there is link to it, where certain users can access it.

2.  If i design my report on different machine, then i publish/deploy to the servername/reports using, lets say the same account that can access sharepoint, where the link is

3   http://servername//reports/ portal. You must be able to use the rights groups created by Azure AD "website.com" to manage the portal's rights.

Can these things be done? IF so, how?
