That is a really vague question, as most things involved in computers involve technical details.
It would be like, "What does a gaming PC cost?", and the reply would be, "That depends on what kind of gaming you want to do."
For example, "AR Content for a large body of gamers", to me that sounds like you want to know what Nintendo pays to host Pokemon Go at various times in the lifecycle.
A quick google search poses no results, except.. "It's complicated".
You are talking about server processing, response, and ISP time. Is there a server admin forum, because you'd be better off asking somebody who is in the cloud industry on server performance / cost and hosting solutions.
BUT WAIT!
I found an answer...
