Today, AWS announces the availability of KNFSD File Cache, an open-source, Apache-2.0 licensed solution for deploying a scalable, high-speed Network File System (NFS) cache on AWS. KNFSD File Cache mounts exports from one or more source NFS servers, whether on-premises, in another AWS Availability Zone or Region, or in another cloud over AWS Interconnect - multicloud, and re-exports them to NFS clients in AWS. You can front multiple on-premises filers, in-cloud file systems such as Amazon FSx for OpenZFS and Amazon FSx for NetApp ONTAP, and any other NFS v3, v4.1, or v4.2 compliant filer.
