s3fs
FUSE-based file system backed by Amazon S3
...Allows random writes and appends, large files via multi-part upload, and renames via server-side copy. User-specified regions, including Amazon GovCloud. Many systems provide pre-built packages. s3fs supports the standard AWS credentials file stored in the credentials folder. Alternatively, s3fs supports a custom passwd file. The default location for the s3fs password file can be created. Generally S3 cannot offer the same performance or semantics as a local file system.
