Can we have a Cloud Storage as backend

[ECMGURUS]

Instead of using In-Memory or File System, can we use some kind of cloud storage backend for persistent storage of files? That way, even if the docker container is restarted, the storage remains and it offers unlimited/cheaper storage compared to other options. We will have security to the files that we want to index as well. Please consider this option.
Amazon S3
Google Cloud GCS
Azure Storage
etc...
