Configuration changes

Acquia Cloud Platform uses configuration management systems to ensure stability and consistency. As a result, Acquia Cloud Platform doesn’t support custom operating system configuration changes, nor does Acquia make arbitrary customizations to configuration files such as Apache virtual hosts. Among other problems, such changes can cause your installation to fall outside the test suite for releases and upgrades, and any changes may not reliably survive a relaunch.

Supported customizations include:
