Alibaba Cloud sets default quotas on the cloud resources and API operations for each Alibaba Cloud account. This topic describes the quota items and their default values of Express Connect, as well as whether the quotas are adjustable.
Quotas are set on a per-region or per-account basis. Quotas 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 QPS limits.
- Privileges: the permissions to use advanced features. Privileges are granted by Alibaba Cloud to an account.
Express Connect is subject to general quotas, API rate limits, and privileges. You can apply for increases on some of the quotas. You can view and manage quotas in Alibaba Cloud Quota Center or in the Express Connect console. For more information about how to manage quotas, see Manage Express Connect quotas.
