Connection to aws rds mysql

Thanks!

But I didn't find AWS RDS MySql in the list, which you proposed to me.

Maybe I should clarify a bit about my problem:

   I have a PBI desktop file, Also I have a PBI file on the report server, and when I need to update the file on the server, I need to do 2 operations: 1) refresh in desktop file --- just to get data in graphics updated.

                                         2) publish in desktop file ---- publish the file to report server.

As the data source for my PBI file, I use the AWS RDS MySQL server. 

So, I want to automate these things. And I found out, that in the file on the report server I can do an automated refresh. I tried, but unfortunately, I understood, that without gateway I can't do it (or at least don't know how to do it).

So, I wonder why it is so? Why I should use an additional server for installing on-premise, while my RDS server always online? And why in desktop version all works well?
If anyone can help me, I really appreciate it.

Thanks, guys!
