Built on Amazon Web Services, Engine Yard Orchestra is for deploying PHP apps to the cloud. Developers can build applications with popular PHP frameworks and deploy from Git or Subversion. Applications can also be deployed with built-in content management systems, such as Joomla, Drupal, and WordPress. The core platform is built on PHP 5.3 and the Nginx Web server. Applications automatically scale with traffic and resource usage. A load balancer distributes loads across available instances, and an HTTP caching-mesh capability enables faster loading and response time. The platform is good for running APIs, Web services, and mobile and Facebook apps alike, according to Engine Yard.
