It doesn't wrap Amazon's S3 it just provides an S3 compatible API. Our use case was to have application code that only interacted with file storage through a single S3-api compatible filesystem adapter. Then we'd either spin up minio in a docker container in those offline deployment scenarios and feed that container's info into the applications environment variables, or when deployed to the internet we'd feed it real AWS S3 connection info. The application code then never needed to know or care where the files lived which meant that code didn't need to have conditionals to use regular filesystem libraries in one code path and S3 adapters in a different path. This also naturally prevented some of our junior devs from trying to do things that instinctually made sense when working directly with a filesystem but is impossible to do on S3 (like trying to unzip a file on S3, or symlink or think that you have cheap and easy move operations).
