If http://www.databasepublish.com/blog/presentation-scaling-drupal-enterprise represents Drupal’s enterprise thinking, Drupal doesn’t “get” enterprise.
Drupal apparently thinks enterprise is just performance. That misses other important factors where Drupal falls on its face. For example:
- It’s security model is stuck in a departmental model. At my work, we looked into an enterprise Drupal calendar, but we passed because it requires fantastic workarounds just to roughly approximate enterprise security.
- Manageability is improving with the Aegir hosting system, but this just simplifies base management tasks. Enterprise Drupal is still a collection of discrete, departmental-class web systems, each of which has substantially independent configuration.
Drupal has its place in the enterprise for certain departmental solutions. But it’s a huge stretch to intimate that Drupal is “enterprise software.”
