An Infrastructure Arms Race Is Fueling the Future of Gaming

The future of gaming lives inside metal cages, if you believe some of the biggest gaming companies out there. Piled on hardware racks, blinking with little green lights, its calculated inside stacked-together computers and pumped out of a remote server through big underground tubes. It is distributed across the globeShanghai, London, Prague, Virginiafrom nondescript, city block-sized architectural monoliths. To see it up close, you would need to pass through multiple levels of security.

Over the last two years, it seems every major gaming and tech company has launched a cloud gaming service: Microsofts Project xCloud, Sonys PlayStation Now, Googles Stadia, Nvidias GeForce Now, Tencents Start. Facebook and Amazon are reportedly sniffing around, too. For a monthly fee$10 to $35users can play a library of videogames on demand, streamed to their phone, television, console, computer, or tablet.

Big tech expects cloud gaming to be white hot, if the major ante theyve pushed into it says anything. Like a lot of cutting-edge tech, it cloaks the technology behind the magic, giving you the impression that you're barely dealing with hardware at all. It's a charming effect. Don't fall for it. In interviews with WIRED, the people behind some of cloud gamings biggest services and data center organizations lifted the curtain on the infrastructure powering these immaterial services. Many agree that, as competition becomes more fierce, and cloud gaming sees mass adoption, success in cloud gaming could mean an infrastructure arms race.

We live in a culture of instant when it comes to any kind of electronic media, says Microsoft corporate vice president of cloud gaming Kareem Choudhry. He was winding up for the cloud gaming pitch: Of the worlds eight billion human beings, over two billion are gamers. Gaming is as culturally impactful as music, television, and movies. And until cloud gaming, there was no mass-market Netflix for videogameson-demand content thats device-agnostic. Besides, says Choudhry, We know were not going to sell two billion consoles.

Take something as simple as piloting the Witcher 3s Geralt a few steps to the left in a cloud gaming service. Flicking the controllers analog stock initiates a ping-pong of invisible signals to an uber-powerful and remote computer: from the controller, through the internet, to the cloud gaming services nearest data center and then the cloud gaming server, which processes your action and calculates a new game statewhich it then feeds back to your monitor, where Geralt has inched closer to the bar.

Cloud gaming is software as a service. That service is two-pronged: a library of videogames the cloud service provider has negotiated with game publishers, and a way to stream those games over the internet. This culture of instant has generated big demands for that delivery service: low-latency, so you can dodge a combo in Street Fighter V; and no packet loss, so your very alive-seeming Overwatch character isnt suddenly dead. While a services performance depends in part on your home internet situationand will change with the arrival of 5G, at least on your phonemuch of its lasting success will hinge on data taking as short and uninterrupted a round trip as possible from your hardware to a data center.

Its everything besides bandwidth, second only to bandwidth, says David Linthicum, Deloittes chief cloud strategy officer, of the importance of data centers to cloud gaming competitors. The company that provides the fastest infrastructure and the largest points of presence in data centers around the world. Thats gonna go to whos gonna be successful.

If youre playing God of War in Egypt, but your cloud gaming services closest data center is in Qatar, there might be enough delay between your inputs and Kratoss movements to emotionally disconnect you from gameplay. Sending an ax-slash signal from the United States East to West Coast takes 40 to 60 milliseconds; enough time for frustration to creep in. To give as many people as possible the best latency possible, you need to own or rent space from a lot of well-located data centers. The slightest increase in latency, lag, or jitter can send early adopters away from these new platforms and back to their consoles and PCs, says Jennifer Curry, the senior vice president of product and technology at data center colocation company INAP. Just 20 to 30 additional milliseconds can be the difference between a top-tier and unviable service.

Yet cloud-gaming-capable data centers can cost hundreds of millions of dollars to build. They need to be central to large populationsinside or nearby citiesrequire fiber optic connectivity, and eat up immense amounts of power, including for cooling. They can be huge; Microsoft owns a Dublin data center thats 550,000 square feet, nearly 10 football fields. On top of size and location, these facilities require top-of-the-line hardware, security, maintenance. And gaming servers are specialized with powerful graphics cards and other high-octane tech ensuring low latency, beyond what might be expected from a server that hosts Google Docs. Its a gargantuan risk to invest all of that cash in infrastructure supporting a not-quite-mainstream-yet technology. At the dawn of cloud gaming, some tech companies are better set up than others to succeed in an industry so reliant on infrastructure.
