A Cloud Enterprise Network (CEN) instance is the fundamental resource for managing an integrated network. A CEN instance manages one network and can span one or more regions. Before enabling connectivity between network instances, call the CreateCen operation to create a CEN instance.
Operation description
The CreateCen operation is asynchronous. The system returns a CEN instance ID before the CEN instance is fully created, while the creation task continues in the background. You can call the DescribeCens operation to query the status of the CEN instance.
If the CEN instance is in the Creating state, the CEN instance is being created. In this state, you can only query the CEN instance but cannot perform other operations on it.
If the CEN instance is in the Active state, the CEN instance is created.
