A service quota is the maximum number of cloud resources or operations that an Alibaba Cloud account can use. This topic describes the quotas for NAT Gateway, their default values, and whether you can request an increase.
Alibaba Cloud service quotas are typically limited by account or region. They are categorized into three types:
General quota: The maximum number of cloud resources that an Alibaba Cloud account can use.
