Billing Mode

TencentDB for SQL Server offers the following billing mode:
Billing Mode
Payment Mode
Applicable Scenarios
Yearly/monthly subscription
Prepaid mode, which means that you pay the fee when you create an instance.
Suitable for long-term needs with relatively stable traffic volume. The fee is lower compared to pay-as-you-go mode, and the longer the purchase period, the more discounts you get.
Pay-as-you-go
Postpaid mode, which means that you apply for resources on demand first, and you are charged based on your actual resource usage during settlement.
Note:
Fees are settled hourly. If the resources are used for less than 1 hour, fees are charged based on 1 hour.
It is suitable for business scenarios with large instantaneous fluctuations in business volume. The instance can be released immediately after use to save costs.

If you enable additional disk I/O performance, it involves additional charges. For detailed feature introduction and billing information, see Additional Disk I/O Performance Billing.
