Minio is an opensource object storage system that is functionally compatible with Amazon's S3 service. It's written in go and aims for minimalism, scalability, and reliability with automatic erasure coding and checksums of data. If you can throw it in an S3 bucket, you can throw it in a Minio bucket. Objects top out at 5TB in size. The executable itself tops out at 22 MB in size. Even has an online webapp that lets you browse buckets and their contents.
