This topic describes how to view and increase quotas. You can view your privileges and quotas in the ECS console. Instance type-specific quotas are allocated based on zones. You can apply for quota increases based on your needs.

Background information

Privileges and quotas of your account vary based on the usage of your ECS resources. Instance type-specific quotas are allocated based on the zone, instance type, billing method, and network type. The base quotas are automatically allocated and adjusted by the system. When you create ECS instances within the base quota, the success rate is high. If the total quota cannot meet your requirements, you can apply to increase it.

Quotas by Instance Type tab

The following table describes the parameters in the preceding figure.

No. Section Description
Instance type quota for each zone The instance type-specific quotas for each zone of the current region under your Alibaba Cloud account.
vCPU-based total quota for all instance types in a zone The maximum number of vCPUs that can be assigned to all instance types. You can view the vCPU-based total quota for instances of all instance types that use a specific billing method and specific network type in each zone. For example, you can view the maximum number of vCPUs that can be assigned to VPC-type subscription instances of all instance types in Qingdao Zone C.
Attributes of an instance type The base and total quotas are allocated based on the attributes of the instance type, such as Zone, Instance Type, Billing Method, and Network Type.
Quota Unit The unit of the quotas for all instance types/the quotas for a single instance type in a zone is vCPU. The unit of the quota of a single instance type is instance.
Usage The used base quota and the total quota. Information about the usage of the base quota and the total quota is displayed when you move the pointer over the Usage column in each row.
Note When an ECS instance is created, the base quota is used preferentially.
Base Quota The base quota is automatically adjusted and allocated before the tenth day of each month based on the usage of your ECS resources. You cannot increase the base quota manually.
Note When you create ECS instances within the base quota, the availability of required resources is guaranteed.
Total Quota The total quota contains the base quota and other quotas. The total quota is greater than or equal to the base quota. The total quota is automatically adjusted along with the base quota before the tenth day of each month.

If the number of vCPUs or instances under your account reaches the total quota, you cannot purchase new instances.

If you need more ECS instances, you can apply for increasing the total quota. After the total quota is increased to a specified value, the system will keep the total quota from falling below this value when the system automatically adjusts the total quota within three or more months.

Note When you create ECS instances beyond the base quota, the availability of required resources is not guaranteed.
