This came up during the meeting with the LTS, when the plans of moving the Dataverse production onto a cloud were discussed. S3 will have to be supported as the main production storage mechanism, since local disk space will no longer be available.

The existing swift driver can be used as a basic model.

#3919, just opened, is not a direct dependency, but, for the purposes of this production move both of the issues will need to be addressed at the same time. As we will not be able to continue storing the dataset-level files, like cached exports, etc., for the same reason as the above - as local file system space will no longer be there.
