As reported by Ars Technica, Amazon has officially confirmed that the titles in the Luna service catalog will run directly through an instance of Windows. This aspect will offer teams great advantages in developing games for the cloud platform.
Amazon Luna will use a standard “G4” instance of Amazon EC2, equipped with Nvidia’s Tensor Core T4 GPU, with development studios that will therefore not have to convert their titles for other operating systems as happens, for example, on Google Stadia.
Therefore, it is significantly different from that used by the Mountain View house for Stadia, which uses Linux-based instances and exploits the Vulkan API—prompting development studios to do extra work to convert their titles for Stadia (with possible problems that can occur depending on the time spent in the optimization phase). This will not happen for Luna, however, as Amazon’s cloud platform will use a “standard” Windows-based structure.
Amazon has also worked hard to offer its customers compatibility with iOS devices (considered essential for the service), trying to “circumvent” Apple’s strict rules that have created many direct headaches. Competitors like Stadia (in fact), Microsoft’s xCloud, and Nvidia’s GeForce Now.
The US company has created a real Luna web-app to be used directly from the iOS operating system’s browser.
“We are already working with the Safari team to ensure that our subscribers get great support via the web app, including adding controllers,” said George Tsipolitis, Head of Engineering at Luna. “As soon as we’ve perfected it, we’ll bring it to Android devices as well.”
Tsipolitis explained that any additional overhead from running in a web browser would not be significant for a streaming game service like Luna. The manager added that the open-source WebRTC protocol that Luna uses for server-to-player communication (and vice versa) works identically in the browser and a native app, so there are no substantial differences in an application.
This protocol will also allow Luna to monitor the various players’ network conditions and adjust the streaming quality in real-time to provide “low latency and high fidelity” gaming sessions compared to experience, not via streaming. Subscriptions for an Amazon Luna road test are already available in the United States (by invitation only), with the service officially starting in October in Early Access. At the moment, there is no concrete information on the possible debut in Europe.
