What engineers like:
Exposes cloud object storage (S3 & S3 compatible, GCS, Azure Storage) as if it were a POSIX compatible filesystem with standard commands like copy, list, remove, etc. Appears as a new mounted filesystem plus a CLI for direct interaction (which offers better performance than a FUSE mount). Supports metadata like permissions, links, users, etc.
Trade-offs & limitations:
No Arm binaries. Be aware that whilst CunoFS works around the object storage write-once limitation, it may not be efficient.
Best suited for:
Developers using cloud object storage should consider CunoFS
