Microsoft confirms that it is offering developers access to free dedicated multiplayer servers for the Xbox One.
Xbox Live Compute – dedicated servers! If you have played a lot of multiplayer games, you know that playing on dedicated game servers has advantages over peer-to-peer gameplay. With server-based multiplayer gaming, not only can more players play the game (think hundreds of players simultaneously), the gameplay will be much more reliable for the players. No more host migration interruptions, suboptimal experiences for the host, home network NAT constraints, or player cheating! Additionally, Xbox Live Compute can be utilized to persist game state so that your squad can live to fight another day without losing any progress. A great example of a game that is using Xbox Live Compute for their dedicated server multiplayer experience is “Titanfall.” ~Xbox
