Compare Open Orchestra vs. Drupal 8

Open Orchestra is an Open Source CMS built on the full stack framework. For database it uses a MongoDB, a NoSQL store rather than the more typical Relational Databases such as MySQL or PostgreSQL.

Drupal 8 is a partial modernisation of the legacy Drupal CMS with a few parts of Symfony under the hood. Usability improvements were not the focus and to the end user Drupal 8 is very much like Drupal 7.

• Full Stack Symfony implementation with focus on code quality
• NoSQL MongoDB backend allows high performance
• Clean admin UI with drag & drop layout management

• Based on stable legacy with critical APIs in place
• A large number of ready made modules (for Drupal 7)
• Large mass of developers brings stability for purchasers

• Fairly unknown and not widely adopted
• Quite dependent on the efforts of a single company
• Documentation not the best (REST API, for example)

• A custom architecture based on Symfony Components, proprietary module structure
• Usability of admin interface not very good and remains tightly coupled to Drupal
• Suspect to security issues due to custom implementation and popularity (see Drupalgeddon)
