You can filter and view instance quotas by region, zone, instance type, billing method,
and network type. Instance quotas are classified into the following types:
- Instance type-specific quota: You can click Instance Type in the upper-left drop-down list to view the instance type-specific quota that specifies
the quota for instances of a specified instance type and a specified network type
that use a specified billing method in a specified region and zone.
Note Quotas for instances of the classic network type are displayed only when the classic
network is available in the region. You can check whether the classic network is available
in the region on the Privileges tab.
- Zone-specific vCPU-based total quota for all instance types: You can click All in the upper-left drop-down list to view the zone-specific vCPU-based total quota
for all instance types that specifies the maximum number of vCPUs that can be assigned
to instances of all instance types and a specified network type that use a specified
billing method in a specified region and 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 Hangzhou Zone H.

Quota Unit |
- Instance type-specific quota: The displayed value is the number of instances.
- Zone-specific vCPU-based total quota for all instance types: The displayed value is
the number of vCPUs.

Total Quota |
Total quotas include base quotas, reserved quotas, and other quotas. Total quotas
are automatically adjusted along with base quotas before the tenth day of each month.
If the number of instances or vCPUs 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 keeps the total
quota from falling below this value when the system automatically adjusts the total
quota within at least 30 days.
Note When you create ECS instances beyond the base quota, the availability of required
resources is not guaranteed.
|
Reserved Quota |
Reserved quotas specify the amounts of instance resources reserved by resource reservations.
When you create instances within a reserved quota, the requested resources are guaranteed.
You can create the following resource reservations to increase reserved quotas:
|
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 The base quota is used preferentially when you create instances. When you create instances
within the base quota, their corresponding resources are guaranteed to be available.
