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 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 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 QPS limits.
Privileges: the permissions to use advanced features. Privileges are granted by Alibaba Cloud to an account.
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.
