@britt If you need cheap S3 check out Object Storage at #Hetzner (https://hetzner.com) All your Data stored for €5.99. I run a nginx server as proxy and cache to safe Traffic. Works great so far! For a working config, DM me.
You can get a Server to handle the database and system, too, but maybe you have to use the Helsinki data-center as they are quite sold out currently. Everyone is fleeing the US.
No, I‘m not associated with them, just running nearly 800 machines there 😁
