Creating an Application

Scenarios

An application groups identical or similar components based on service requirements. After an application is created, you can add sub-applications and components to it.

Precautions

If the large-scale application structure is selected, you can configure sub-applications.

Nodes of the same level under an application or sub-application cannot contain sub-applications and components at the same time.
