You could try s3fs: https://github.com/s3fs-fuse/s3fs-fuse If the archive is very large, you might not want to pay for egress, so you could consider running FITS on an EC2 instance.

I'm planning a large-scale digitization project for the physicals that haven't been digitized yet, but the digital collection consists of both born-digital material and files that have been digitized from the physical collection at various points over the last 25 years. I've been requested to re-digitize files that don't meet modern standards, so I need to run FITS over the entire digital archive. The hang-up is that the archive lives in an Amazon S3 bucket which is the backend of the system we use to serve files to clients. I can't figure out how to point FITS at the bucket, since it's not mounted to my local system, and I can't format the path properly. Has anyone else tried this? Thanks, Chris
