For more information about Drupal terms and terminology, see the [Drupal term index](/definitions).

Each [environment](/acquia-cloud-platform/manage-apps/environments) in a sitegroup on the Cloud Platform has a unique sitename. The sitename naming convention consists of the sitegroup and the abbreviated environment name.

For example, if the name of the sitegroup is `acquia`, and it has the three standard environments (development, stage, and production), the website can have three [docroot](/definitions/docroot) directories. Those directories are respectively named `acquiadev`, `acquiastg`, and `acquiaprod`.

Naming requirements for permanent environments
----------------------------------------------

Sitenames for permanent environments have the following naming requirements:

*   Total length can be no more than 16 characters
*   The environment part of the sitename can be no more than 10 characters
*   Must consist of alphanumeric characters; underscores, spaces, and special characters aren’t allowed
*   All alphanumeric characters must be lowercase
*   Must not begin with a number

Note

Production environment sitenames generally don’t include the environment abbreviation `prod`. As a result, the production environment’s sitename is often the same as its sitegroup.

Naming requirements for on-demand environments
----------------------------------------------

[On-demand environments](/acquia-cloud-platform/features/cd) are named sequentially (`example.ode1`, `example.ode2`, `example.ode3`) based on the sitegroup name.
