Alibaba Cloud sets default quotas on the cloud resources and API operations for each Alibaba Cloud account. You can apply for increases in some of the quotas based on your business requirements. This topic describes the quota items and their default values of Smart Access Gateway (SAG), as well as whether the quotas are adjustable.
Alibaba Cloud service quotas are typically applied on a per-account or per-region basis and fall into the following categories:
General quota: The maximum amount of a specific cloud resource that an Alibaba Cloud account can use.
API rate limit: The maximum frequency, measured in queries per second (QPS), that an Alibaba Cloud account can call a service API.
Privilege: The authorization granted by Alibaba Cloud to an account to use specific features.
Smart Access Gateway has general quotas, some of which are adjustable. You can view your current quotas or request an increase by logging in to the SAG console. For detailed instructions, see Manage SAG quotas.
