There have been requests for High Availability (HA) for SFTP Gateway on Azure.
Unfortunately, this feature is not available yet (as it is for our AWS product).
Currently, we are developing our product against the NFS preview.
This NFS preview offers NFS 4.1 which has full POSIX file system support. This is a dependency for syncing local state (home directories, configuration files) between member servers.
We hope to have a High Availability feature shortly after NFS 4.1 becomes generally available.
