Perhaps most intriguing, however, is that Xbox One gives game developers the ability to access Microsoft’s Azure cloud computing platform. That leads to a few obvious and immediate applications: All your downloaded and installed games and achievements are synced to the cloud and can be accessed and played without interruption on any Xbox One you sign in to; stable,
dedicated servers for every multiplayer game rather than the notoriously fragile practice of hosting matches on one participant’s console; even multiplayer matches that can grow to 64, even 128 participants, rather than the usual limit of 16 or 32.
