Some Drupal contributed modules are incompatible with Cloud Platform, or may require special configuration or care. For more information, see Modules and applications incompatible with Cloud Platform.

Configuration changes

The Cloud Platform uses configuration management systems to ensure stability and consistency. As a result, 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:
