PHP 7 support note

  • Drupal 8 - PHP 7 is fully supported on Drupal 8, and the official Drupal core test suite passes for all supported database engines (including MySQL, SQLite, and PostgreSQL). For details, see Support PHP 7 on Drupal.org.
  • Drupal 7 - Drupal core officially supports PHP 7. Acquia recommends fully testing before upgrading your production website, as there are several backwards incompatible changes.

Acquia Cloud also includes the following items:

  • Common Linux command-line utilities
  • Standard networking tools (including curl, wget, and traceroute)
  • Performance analysis tools (including ps, top, and strace).
  • Common PEAR and PECL libraries
  • Common PHP modules (including PDO, FreeTDS, OpenSSL, json, curl, and xml). For detailed information, go to your Drupal website’s PHP information page at /admin/reports/status/php

Unsupported software

Acquia Cloud does not support the following software:

  • Moodle (not compatible with high availability)
  • piwik (we have repeatedly seen this cause performance issues)
  • Any non-Drupal Content Management System (CMS)
  • CA Single Sign-on (formerly CA SiteMinder)

The following software cannot be installed on Acquia Cloud:

  • Non-standard database software, such as Oracle or Microsoft SQL Server
  • Custom daemons or services, such as Jabber or Microsoft Exchange
  • Custom package installations that require apt-get

You can still install custom executables using your code repository.

Some Drupal contributed modules are incompatible with Acquia Cloud, or may require special configuration or care. For more information, see Module incompatibilities with Acquia Cloud.

Configuration changes

The Acquia Cloud platform uses configuration management systems to ensure stability and consistency. As a result, we do not support custom OS configuration changes, nor are we able to make arbitrary customizations to configuration files such as Apache virtualhosts. 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:
