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 PrivateLink, as well as whether the quotas are adjustable.
Quotas
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 within 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.
PrivateLink is subject to general quotas, API rate limits, and privileges. You can apply for increases on some of the quotas. You can log on to the Quota Center console page or VPC Quota Management page to view quotas or request a quota increase. For more information about how to manage PrivateLink quotas, see Manage PrivateLink quotas.
General quotas
