Thanks to Azure and Game Stack developer tools Xbox Live is also coming on the devices Android e iOS.
Microsoft revealed the news during the GDC 2019, declaring that Game Stack will make all its tools and services available within a unique ecosystem. This includes Azure, DirectX, Havock, Xbox Live and more.
Furthermore, the cloud plays "a fundamental role for Game Stack," with Azure able to bring "a great gaming experience" to players all over the world. Microsoft is totally committed to the cloud and its Project xCloud streaming technology will allow people to play Microsoft games "wherever they want, whenever they want, on whatever device they want".
This is the first step in bringing XBL to all devices. The company also wants Xbox Game Pass on every possible device, so this is a great start.
