How does Lemmy/Mastodon/Fediverse store videos and images? (programming.dev)

As I was browsing lemmy and the fediverse at large, this question kept popping into my head.

Since multimedia files have a much bigger footprint than raw text, it made me feel worried since as time goes, massive resources will be needed to keep up with the big data coming in.

I do wonder if the instances have taken the route of the cloud and just decided to put all of it in something like AWS S3? Or maybe they use self hosted storage with something like minio for object storage?

This will differ greatly from instance to instance. The people running lemmy.world have published some info on their infrastructure. My instance is running on a rather small VPS with 100GB storage, but I will have to rethink my solution rather soon as images and videos from my subbed communities [Edit: which are stored on outside sites] are eating around a gigabyte per day and I think this is likely to increase.

Edit: I want to clarify that I was partially wrong - Lemmy only locally caches content which is hosted on outside sites (e.g. imgur). It does not cache content that was directly uploaded to another Lemmy instance and just embeds the source media.

Maybe have users use an outside image provider, like imgchest or gfycat or whatever?

This is the best idea in my opinion. Even on Reddit people used Imgur a bunch. It would be cool if either Lenny itself, or the various apps that have sprung up tied into an API for Imgur or similar to store pictures/videos, then it would be seamless to the end user.

EDIT: looks like Memmy on iOS actually already does this!
