Ubuntu now allows you to make use of scaleable Android on the cloud. That means just like you stream Word in the form of Google Docs, you can stream your Android apps and ecosystem on your workstation. You can even stream Android games from your device. Reminds of Google's own Stadia, right ? Anbox Cloud works somewhat similar. But it is more than just games. Ubuntu says it is for the end users.
In simple words, it is Android you can take anywhere, conditions apply 😉
