Under the hood: Meta’s cloud gaming infrastructure

The promise of cloud gaming is a promise to democratize gaming. Anyone who loves games should be able to enjoy them and share the experience with their friends, no matter where they’re located, and even if they don’t have the latest, most expensive gaming hardware. Facebook launched its cloud gaming platform in 2020 to give anyone on Facebook instant access to native Android and Windows games across every screen and web browser.

Creating the unprecedented access offered by cloud gaming required engineers at Meta to rise to new challenges and develop a growing hardware infrastructure capable of delivering quality game experiences to people all over the world.

But gaming itself is also evolving. From new 3D experiences like AR and VR to what will eventually become the metaverse, people all over the world want to play increasingly immersive games as seamlessly and easily as possible. While it will take a massive effort across the industry to bring the metaverse to fruition, we believe creating the infrastructure and solving the challenges of cloud gaming are pointing us toward solutions for the metaverse as well.
