Inside Pantheon: the Valhalla filesystem | Pantheon

by holyver
At Pantheon, when we look at challenges Drupal projects face, we don't only do what's worked well-enough in existing deployments. We ask ourselves how we can transcend some of the challenges entirely. How Drupal stores files is no exception. So, when we started building the next generation of Pantheon (now launched), we looked at our options -- and then built a solution entirely focused on the needs of Drupal developers.
