Minio is an S3-compatible object store with optional distributed storage capability.
This appears to just be an object layer. I supposed you could build an access layer on top similar to Minio.
It looks like it isn't as user friendly as Minio and it doesn't provide an S3-compatible API like Minio but it looks to be more scalable and less opinionated than Minio (which for example forces the authors' replication preferences on you by hard coding them).
