Drupal-based production environments in Acquia Cloud Enterprise include the ability for you to scale server sizes, based on need, by using the Acquia Cloud user interface. Acquia Cloud Enterprise includes Cloud Service Management (CSM) as an optional part of new Medium and Large Acquia Cloud Enterprise subscriptions, providing you with direct control of the scaling of your Acquia Cloud-hosted application. Note that this feature does not affect the monitoring that Acquia does on its own to monitor the health of the Acquia Cloud managed application stack, and Acquia Support can continue to perform emergency scaling as needed.
Acquia Cloud customers with Cloud Service Management enabled can view statistics for CPU utilization, memory utilization, and PHP process count in the Acquia Cloud management interface. The management console will also display PHP Max Children Reached error messages. By combining information about your website's performance during peak traffic periods with PHP Max Children Reached errors, you can determine if you should scale up your web tier.
When you scale up a production environment, you will be billed at the daily rate for a temporary increase until you scale the environment back to its minimum size. If you want to permanently increase your minimum size, contact your Account Manager; the change will be billed at the annual rate until the end of your contract term.
