I would like to have a license advice given the following situation.
We have our data on-premise and use the powerbi service, we run the gateway service. Employees with access need the powerbi pro license and we currently use it this way for a fraction of our employees.
We would also like to distribute powerbi to our students (10000+) and they have an office365 education license. Our data will remain on-premise . We have a school mobile app and would like to integrate powerbi into the mobile app. What would be the best licensing option given the fact we have an own app and would like to embed it, we have sharepoint online, we have sql server 2016 enterprise with reporting services including powerbi. A vital pre-condition is authorization, for instance the students should only be able to see their own individual mark sheet.
