Instance Quota Management Overview
Tencent Cloud imposes certain limits on the quota of the CVM instance purchase quantity for each AZ, billing mode and instance type. CVM quota management provides you with centralized management of instance quotas. Through CVM quota management, you can query the current and used quotas of each instance or apply for an increase in instance quotas based on business needs.
Basic Concepts

Description
Instance Quota
A Tencent Cloud account can apply for the maximum value of instance purchases.
Quota Unit
Quota units are distinguished by instance specifications:
Instance specifications with vCPU < 64 cores, quota unit is number of cores.
Instance specifications with vCPU ≥ 64 cores, quota unit is number of CVM instances.
Current Quota
Current maximum value of instances that can be applied for purchase.
Quota Used
Quota of purchased and used instances.
Apply for Quota
You can apply for a quota increase on the quota management page.
Target Quota
Target quota value applied for. Once the quota application is approved, it will override the original quota value.
Instance Quota Rules
The quota unit for CVM varies by instance specifications. Specific details are as follows:
For instance specifications with vCPU < 64 cores, the quota unit is counted by number of cores.
For example, all SA5 specifications with vCPU less than 64 cores, including SA5.MEDIUM2, SA5.MEDIUM4, SA5.LARGE8, etc., share a total SA5 quota, which is calculated by the number of cores.
For instance specifications with vCPU ≥ 64 cores, the quota unit is counted by number of CVM instances.
For example, the SA5.20XLARGE160 has 80 vCPU cores, so SA5.20XLARGE160 has a separate quota, which will be calculated by the number of CVM instances.
