This section introduces the billing instructions related to the CPU Elastic Scaling feature.

Billing for Automatic Scaling

Fee Calculation

The CPU Elastic Scaling feature uses pay-as-you-go billing mode, where fees are charged on a minute basis and deducted once per hour. Billing Formula = (Unit price x Number of added CPU cores) x Scaling duration (minutes) / 60.

Automatic Scaling Billing Example

1. Suppose a two-node instance in Guangzhou has a CPU with 4 cores. After Automatic Scaling is triggered, it is expanded to 8 cores. The scaling duration is 1 hour. Given that the unit price in Guangzhou is 0.08 USD/core/hour, the total cost would be calculated as follows: 0.08 (Unit price) x 4 (additional CPU cores) x 1 (duration of expansion) = 0.32 USD.
2. Suppose a two-node instance in Guangzhou has a CPU with 2 cores. After Automatic Scaling is triggered, it is expanded to 4 cores, with a scaling duration of 30 minutes. Considering that the unit price in Guangzhou is 0.08 USD/core/hour, the total cost would be calculated as follows: 0.08 (Unit price) x 2 (additional CPU cores) x 30/60 (scaling duration) = 0.08 USD.
Note:
Upon enabling CPU Auto Scaling: you will be billed according to the number of CPU cores added when the elastic scaling is successfully triggered. There will be no additional charges when no scaling is performed.
To mitigate the impact of persistent intermittent peaks, there is a minimum protection time of 10 minutes during auto-scaling. That is, if the auto-scaling lasts for more than 10 minutes, the cost will be calculated based on the actual scaling time. If the auto-scaling lasts no more than 10 minutes, the cost will be calculated with the duration of 10 minutes.

Manual Scaling Billing Description

Fee Calculation

The Manual CPU Elastic Scaling feature adopts the pay-as-you-go billing method, where fees charged on a minute basis and deducted once per hour. Billing Formula = (Unit price x Number of added CPU cores) x Scaling duration (minutes)/60.

Manual Scaling Billing Example

In Beijing, a CPU elastic scaling is manually enabled for a two-node instance with a CPU with 2 cores on 10 AM, with 2 cores added. The manual CPU elastic scaling process is then disabled at 5 PM, which means the scaling lasts for 7 hours. Given that the unit price in Beijing is 0.08 USD/core/hour, the total fee would be: 0.08 (unit price) x 2 (additional CPU cores) x 7 (scaling duration) = 1.12 USD.
Note:
Once Manual CPU Elastic Scaling is started, the number of CPU cores for the instance will immediately increase based on your configurations and fees will be charged synchronously until you disable manual scaling. Therefore, the system will continuously charge since manual scaling is enabled and until it is disabled. For instructions on how to disable manual scaling, please see Disabling Manual Scaling for operation to turn off manual scaling.
