I configured Free Radical to use S3 to serve media assets, like images and videos, almost immediately after launching it. There are compelling reasons to use something like S3 instead of serving those files directly from the Mastodon server, such as freeing that server from getting clogged with a zillion media requests. In theory, it should be cheaper, too. Well. In October 2022, our AWS S3 storage bill was $12.54 for storing about 330GB of media files and serving about 113GB of files to users.
