If you want cheap storage, check out backblaze. Otherwise use s3. I want to do something similar but I need very custom permission/authentication handling so I’m storing things in s3 and using ec2 instances as a proxy, which can also help with caching s3 calls (I don’t want to use Cloud Front). In these ec2 instances I basically have a custom Nginx configuration and that’s it.
