I am working on SeaweedFS. It was originally designed to store images as Facebook Haystack paper, and should be ideal for your use case. See https://github.com/chrislusf/seaweedfs https://github.com/chrislusf/seaweedfs And it already supports S3 API, and other HTTP, FUSE, WebDAV, Hadoop, etc. There should be many existing hardware options that is much cheaper than AWS S3.
