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 attributes such as zones. You can apply for quota increases.

Background information

Privileges and quotas of your account vary with the usage of your ECS resources. Instance type-specific quotas are allocated based on zones, instance types, billing methods, and network types. 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 a total quota cannot meet your requirements, you can apply to increase it.
Note The privileges and quotas feature of some accounts has not been upgraded to the new version. If your Privileges & Quotas page is not consistent with that described in this topic, see Manage privileges and quotas.
Quotas by Instance Type tab

The following table describes the sections in the preceding figure.

No. Section Description
Instance type-specific quota for each zone The instance type-specific quotas for each zone of the current region in your Alibaba Cloud account.
vCPU 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 total quota for instances of all instance types that use a specific billing method and are of a 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 quotas and total quotas are allocated based on the attributes of the instance type, such as the zone, instance type name, billing method, and network type.
Quota Unit The unit of the total quota for all instance types in a zone is vCPUs. The unit of the quota for a single instance type is instances.
Usage The used base quota and total quota. The usage of the base quota and total quota is displayed when you move the pointer over the Usage column corresponding to each row.
Note When an ECS instance is created, the base quota is used preferentially.
Base Quota Base quotas are automatically adjusted and allocated before the tenth day of each month based on the usage of your ECS resources. You cannot apply to increase the base quotas.
Note When you create ECS instances within the base quota, the availability of required resources is guaranteed.
Total Quota A total quota consists of a base quota and other quotas. Therefore, the total quota is greater than or equal to the base quota. Total quotas are automatically adjusted along with base quotas before the tenth day of each month.

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

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

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