Earlier this week news broke that the Xbox One version of Call of Duty: Ghosts would be running on dedicated servers thanks to the Xbox One cloud functionality. Last night, Infinity Ward went on to discuss why past iterations of Call of Duty were forced to be on peer-to-peer connections. This morning, we have more details on other current and next generation console's regarding multiplayer servers.
In an interview with EuroGamer, Mark Rubin has confirmed that dedicated servers are reserved for Xbox One and PC only, claiming the Cloud as the soul reason for the Xbox One dedicated servers (a subset of the Azure cloud called "Thunderhead"). PC platform Call of Duty's have had dedicated servers in the past due to their smaller installation base, so nothing changes here.
As for the PlayStation 3, PlayStation 4, Xbox 360 and Wii U versions? Well, Mark Rubin wouldn't confirm anything (still), but did go on to say that the Xbox 360 could not utilize the Azure cloud service that the Xbox One has access to.
"Those [Xbox One and PC] are the only platforms we're talking about at the moment"
"Microsoft's 300,000 server Xbox Live Cloud is a subset of Microsoft's Azure platform. The part reserved for Xbox Live is called Thunderhead, which can only be used for Xbox One - not PC or even Xbox 360."
Now yes, Sony has the ability to run a cloud service, they have even spoke about this in the past. But Sony's cloud service is in no way as large, functional or established as Microsofts own network. In fact, the only competitor to Microsofts Cloud service is Google in terms of sheer size and availability across the world.
With that said, Infinity Ward and Activison could be working out a deal with Sony in order to get their cloud service functioning on the PlayStation 4; the delay in information could be an indication of that.
As for the Xbox 360 and PlayStation 3 - Activison hasn't given players dedicated servers during the peak of the series popularity on those platforms, so the prospect of them ponying up the cash and infrastructure now is slim to none (especially when 95% of the player based couldn't care nor notice the peer-2-peer connection). Given the prospect of those platforms receiving dedicated servers, does the Wii U really need mention?
Those are all just assumptions though. Infinity Ward and Activison may finally feel the pressure of Battlefield 4 and TitanFall offering up dedicated servers. But with that said, even Respawn hasn't confirmed dedicated servers for the Xbox 360 version of TitanFall due to the lack of cloud functionality. It seems price is of the importance this time around, and if the publisher has the option to utilize Microsoft's cloud, their own dedicated servers become an after thought.
