Your Cloud Platform Environments page provides information and controls for your Cloud Platform environments.
Filtering environments
If you have many environments, you can use the Filter Environments field on the Applications > Environments page to find the environment that you want to work with.
Start typing in the Filter Environments field; only environments whose names match your filter string are displayed on the Environments page. Clear the Filter Environments field to display all the environments of your application.
Renaming an environment
By default, an application has three environments named Dev, Stage, and Prod. Environment names may be different, but the names must be unique within an application.
To rename an environment:
On the Overview page, click Rename.
Enter a new name for the environment.
Click Rename.
