As a consultant specializing in enterprise Drupal, I often find myself answering a relatively small (and consistent) set of questions about the Drupal platform early on in any engagement. Many of the larger Drupal sites are media and publishing oriented, which makes these questions even more common across projects. As a result, I've started to compile a list of most common Drupal questions and the answers I've been able to provide. First up is the most common concern enterprises have about Drupal - scalability.
