I wish to share a game I created that I've uploaded to a cloud/server?

The normal method would be to create a torrent linking to the file on my PC, but then I'd have to leave my computer on day & night for about a week until enough people have downloaded it to create a reliable seed.

It would be MUCH nicer if people could download the file VIA TORRENT directly from the cloud (I am aware I can just post a share link, but then I must host the file forever).

Is this even possible? I searched online for an answer but all results are of how to download directly TO a cloud, not share FROM it.

TIA

All you need to do is download it to one user who stays on line 24/7 and has sufficient bandwidth to keep seeding the file

what you need is called a "seedbox".
you might also find some ideas here: https://www.reddit.com/r/seedboxes/comments/r2gmof/recommendation_for_a_simple_and_cheap_cloud_based/
also you dont have to keep your pc on 24/7, if the game is good - other peers will keep seeding. even if you seed during the day it should help and keep your torrent alive.
