I'm just wondering whether GameSparks offer hosts dedicated servers for say UE4 games, or whether if I am to use GameSparks, I would need to find my own services to host dedicated servers and connect to GameSparks that way.

As an example, PlayFab allows you to host your dedicated server executable file in different regions and automatically scale up and down those servers accordingly. They also offer match making and other features quite similar to GameSparks. If I were to use GameSparks, would I need to either use Amazon EC2 or Photon to host my servers and handle server scaling myself? Or is that something GameSparks can do for me?

Thanks
