Do other groups have the intention to host their project in their cloud for the final demo or just run it locally?
What do you mean host the project in the cloud?
use a hosting service such as Google cloud to host your codebase; in other terms make your application available to the public.
Well for android developers, if it's complete, then the goal is to put it on the Google Play store. For web developers, you can publish it somewhere, if you have a domain name.
Others, no idea.
