Express Connect:Express Connect quotas

更新時間:Aug 30, 2024

Alibaba Cloud sets default quotas on the cloud resources and API operations for each Alibaba Cloud account. You can view your adjustable quotas and apply for a quota adjustment based on your business requirements. This topic describes the quotas of Express Connect and their default values, as well as whether the quotas are adjustable.

Quotas are set on a per-region or per-account basis and are categorized into the following types:

  • General quotas: the limits on cloud resources that are available to an Alibaba Cloud account.

  • API rate limits: the limits on API calls that an Alibaba Cloud account can make in a specific period of time. API rate limits are also known as queries per second (QPS) limits.

  • Privileges: the permissions that are granted to an Alibaba Cloud account to use advanced features.

Express Connect is subject to all three types of quotas: general quotas, API rate limits, and privileges. You can apply for increases in some of the quotas. You can view quotas or apply for a quota increase by logging on to the Quota Center console or the Express Connect console. For more information about how to manage quotas, see Manage Express Connect quotas.

The following table lists the general quotas of Express Connect.

Quotas whose default values are 0 or displayed with hyphens (-) are unavailable by default. The default values of quotas in the following table are for reference only. The actual default values of quotas in the console prevail.
