Acquia Cloud applications run on a Drupal-optimized platform. The core of the platform is an open-source LAMP server stack, combining the Linux (Ubuntu) operating system, Apache web server, MySQL (Percona) database, and PHP programming language with Drupal. The default Acquia Cloud configuration works as-is for most web experiences and other applications. Acquia Cloud provides you with a suite of tools you can use to manage your applications and the domains and environments they run on.
What's an application?
In Acquia Cloud, an application is a software product that implements a web service, such as a Drupal-based web site or a web-accessible API. Application specifically refers to the software product as an entity in itself, separate from the potentially many installations of the application in different environments, such as production, or development, that may use specific domain names, with specific content. Applications have a lifecycle and typically have multiple versions. An application is primarily made up of its program code, such as Drupal core plus contributed and custom modules, along with static assets such as images and stylesheets for its visual theme.
