\nSoftware as a Service, Infrastructure as a Service, Platform as a Service, Communication Platform as a Service, Video Conferencing as a Service, but what about Cloud Gaming as a Service? Several attempts have already been made to create Cloud Gaming, such as Stadia, recently launched by Google. is no stranger to WebRTC<\/a><\/noindex>, but can others use WebRTC in the same way?<\/a><\/noindex><\/p>\n

Thanh Nguyen decided to explore this possibility in his open-source project CloudRetro. CloudRetro is based on Pion, a popular<\/a><\/noindex> WebRTC library in Go (thanks to Shawn<\/a><\/noindex> from the Pion development team for helping with this article). In this article, Thanh reviews the architecture of his project and shares what insights he gained and the challenges he faced during development.<\/p>\n

Introducere<\/h2>\n

\nLast year, when Google announced Stadia, I was blown away. The idea is so unique and innovative that I kept wondering how it was even possible with existing technologies. My desire to understand this topic better led me to create my version of an open-source cloud game. The result was simply fantastic. Below, I would like to share the process of working on my year-long proiectul<\/a><\/noindex>.<\/p>\n

TLDR: a brief slide version with the main points<\/i><\/p>\n

Why Cloud Gaming is the Future<\/h3>\n

\nI believe that Cloud Gaming will soon represent a new generation not only in gaming but also in other areas of IT. Cloud gaming is the pinnacle of the client\/server model. This model maximizes backend management and minimizes frontend workload by placing game logic on a remote server and streaming images\/audio to the client. The server handles heavy processing, so the client is no longer dependent on hardware limitations.<\/p>\n

Google Stadia essentially allows you to play AAA games<\/a><\/noindex> (i.e., high-end blockbuster games) on an interface similar to YouTube. The same methodology can be applied to other heavy offline applications, such as operating systems or 2D\/3D graphic design, so we could reliably run them on low-spec devices across different platforms.<\/p>\n

\nThe future of this technology: imagine if Microsoft Windows 10 worked in the Chrome browser?<\/p>\n

Cloud gaming is technically complex<\/h3>\n

\nGaming is one of the rare fields where a constant quick response from the user is required. If occasionally there is a delay of 2 seconds when clicking on a page, it's acceptable. Live video streams typically lag a few seconds but still provide sufficient usability. However, if a game often lags by 500 ms, playing becomes impossible. Our goal is to achieve an extremely low latency so that the gap between input and media is as minimal as possible. Therefore, the traditional approach to streaming video is not applicable here.<\/p>\n

\"Gaming
\nThe general template for cloud gaming<\/p>\n

The open-source project CloudRetro<\/h2>\n

\nI decided to create a test sample of cloud gaming to check if all this is possible under such strict network limitations. For the proof of concept, I chose Golang as it is the most familiar language to me and well-suited for this implementation for many other reasons, as I found out later. Go is simple and develops very quickly; channels in Go are great for managing multithreading.<\/p>\n

Proiect CloudRetro.io<\/a><\/noindex> \u2013 an open-source cloud gaming service for retro gaming. The goal of the project is to bring the most comfortable gaming experience to traditional retro games and add multiplayer.
\nYou can find more details about the project here: https:\/\/github.com\/giongto35\/cloud-game<\/a><\/noindex>.<\/p>\n

CloudRetro functionality<\/h3>\n

\nTo demonstrate the full power of cloud gaming, CloudRetro uses retro games. This allows for a multitude of unique gaming experiences.<\/p>\n
