There is also ObjectiveFS that supports FUSE and uses S3 for both data and metadata storage, so there is no need to run any metadata nodes. Using S3 instead of a separate database also allows scaling both data and metadata with the performance of the S3 object store.

OFS was a drop in replacement for EFS and tbh it's insanely good value for the problem space.
