Cloud Enterprise Network limits and resource quotas - Cloud Enterprise Network

A service quota defines the maximum number of cloud resources or operations that an Alibaba Cloud account can use. This topic describes the quotas, default values, and adjustment options for Cloud Enterprise Network (CEN).

Quota overview

Alibaba Cloud service quotas apply to specific accounts or regions and are categorized into the following types:

General quotas: The maximum number of cloud resources that an Alibaba Cloud account can use.
API rate limits: The frequency at which an Alibaba Cloud account can call API operations of an Alibaba Cloud service. This is also known as a queries per second (QPS) limit.
Privilege quotas: The permissions that an Alibaba Cloud account is granted by Alibaba Cloud, such as the permission to use a specific feature.

Cloud Enterprise Network (CEN) has general quotas, API rate limits, and privilege quotas. You can also adjust some of the quotas. You can view quotas or request quota increases in the Alibaba Cloud Quota Center console or on the CEN quota management page. For more information, see Increase CEN quotas.

General quotas

The following tables list the general quotas of Cloud Enterprise Network.

Note

For quotas that have a quota name and a quota ID, if the default value in the following tables is different from the value displayed in the console, the value in the console prevails.
You can also obtain information about quotas that have a quota name and a quota ID by calling the ListProductQuotas API operation.
