Depends, I work with a number of HA Drupal sites, and Drupal 7 can do most files in S3 but it still likes to put generated CSS/JS files and tmp files on local disk. In most of these cases (or for already existing sites) it's usually easier to just use NFS or Gluster instead of trying to force everything to S3. upstream issue: https://www.drupal.org/node/2044509 https://www.drupal.org/node/2044509
