If you host your website on Cloud Platform, a realm is the configured space in which an environment exists. Each realm has a unique identifier that’s a required configuration option in some commands issued using the command line interface (CLI), the Cloud Platform API, and Cloud Hooks.
Some common realms include, but aren’t limited to the following:
prod
devcloud
Cloud Platform will display the realm for your subscription in the default domain name included with your
subscription. For example, a default domain name for a website in a Cloud
Platform Professional subscription can be examplesite.devcloud.acquia-sites.com
.
You may also discover the realm for your subscription when accessing your environments using SSH or using SFTP.
The realm for your subscription is also available as the AH_REALM
environment variable.
