Question from a developer:
I get N free hours/$m in free hosting from Amazon/AWS (either through their free tier, or a custom arrangement). How can I use that in PlayFab?

All PlayFab servers, including custom game servers we host for titles, are running in our AWS account, and Amazon isn't going to let us apply any credit/free CPU hours from someone else's AWS account.
But that said, we do provide a set of API calls you can use for external game server hosting (https://api.playfab.com/docs/tutorials/external-game-servers). That would be the way you could benefit from your own free AWS usage, for a title running in PlayFab.
