Node.js environments in Acquia Cloud have the following limitations:

  • Elastic IP Addresses (EIPs) are not supported on production and non-production environments.
  • Non-production environments are shared resources, and are subject to unexpected relaunches.
  • The following features are not supported:
    • Acquia Cloud Shield
    • SSH access into servers
    • Varnish® or custom VCLs
    • Memcached
    • CD environments
  • There is no supported database service or file system asset manager, but you can connect to an external file system/database service, such as a Drupal website.
  • Node.js applications can expose only one port, indicated by process.env.PORT, which is set by Acquia and cannot be overridden. You can, however, use websockets to handle multiple concurrent connections.
