Red Hat isn't the only open source provider pursuing the Platform-as-a-Service market for developers.
This week, Acquia and Engine Yard announced they have joined forces to create a cloud service for Drupal and Ruby on Rails. The new fully managed PaaS will incorporate Acquia's open source web content management system based on Drupal and Engine Yard's Ruby on Rails development platform for the cloud.
The combined offering should attract a decent following. Drupal is a leading open source CMS offering and Ruby on Rails is a leading open source development platform.
