ZeroFS vs. Amazon S3 Files: Differences and Use Cases

ZeroFS and Amazon S3 provide POSIX file systems backed by object storage, but their interfaces have different configurations. S3 Files preserves files as normal S3 objects, while ZeroFS trades direct S3 access for packing, compression, and client-side encryption.

S3 Files connects to a high-performance storage layer where changes flow in both directions, while ZeroFS keeps file data and filesystem metadata on separate paths. Both models utilize client caching, but they exhibit significant differences in file access methods and cost structures.
