Cloud Gaming – What is Cloud Gaming?
Cloud gaming, also known as gaming on demand, is a way of playing video games that represents a paradigm shift in how games are accessed and delivered. Instead of needing a powerful gaming device like a console or gaming PC, cloud gaming allows you to play using any screen you have available – even something as simple as a smartphone or tablet.
The key to cloud gaming is that the heavy computational lifting is done on remote data centers in the cloud, not locally on your device. When you press a button or move your character in a cloud gaming experience, that input gets sent to a faraway data center, which then does all the graphics rendering necessary before streaming back a real-time video to your device. This allows cloud gaming platforms to deliver cutting edge, high-fidelity gaming experiences to devices that would never otherwise have the hardware capabilities needed to run such games locally.
How Does Cloud Gaming Work?
On a technical level, cloud gaming relies on a few vital components working together:
- Data Centers – These are networks of powerful servers running in data centers. They handle all the computationally intensive task like graphics rendering for the games and use GPUs for optimum performance. Companies like Google, Amazon, Microsoft and others operate massive data centers all over the world to facilitate cloud gaming.
- Internet Connectivity – Since all the game processing happens in faraway data centers, fast and stable internet connectivity is essential for a smooth cloud gaming experience. 5G and fiber optic connections are great, but even 4G can work reasonably well if your connection is strong.
- Game Streaming – The concept behind cloud gaming is very much like video streaming. Instead of getting large downloads, the data center sends you a continuous real-time video stream encoded in a compressed format. On your device, all you need is enough bandwidth to decode the stream and render it on your display.
- Input Handling – Your controller, keyboard or touch inputs need to be sent to the data centers near instantly. This input data travels upstream to the cloud so your actions translate into appropriate game responses rendered and streamed back to you. Minimizing input lag is crucial to enjoyable gameplay.
The coming together of broadband internet access, vast computing resources in data centers, advanced GPUs for graphics workloads and increased focus on latency reduction have all finally made cloud gaming a feasible innovation after over a decade of efforts by companies in this space.
