Change configuration instructions
When the configuration of a standard instance is insufficient or oversupply relative to the business load requirement, you can adjust to a more suitable configuration by changing the number and size of the compute nodes.
Change rules
Users can adjust the configuration by clicking the "Change" button on the instance page. When the configuration starts, a new bill will be generated. The cash payment amount will be deducted first before the change. If a refund is generated, the remaining amount will be returned to your account balance. Please note that vouchers used do not support refunds. After submission, the instance will display the "Configuration" flag, which usually takes several minutes to complete the conversion.
Change allocation billing
Pay by volume because it is postpaid, so the allocation does not involve refunds and payments. The next hour's fee is calculated in seconds based on the allocation time. Here we mainly explain the variable allocation billing of annual monthly package examples.
The instance configuration adjustment billing involves the following scenarios:
| Scenarios | Billing Rules |
|---|---|
| Only increase the node specification/only add the number of nodes/increase the node specification and add the number of nodes | Repayment amount = (New configuration monthly price - Old configuration monthly price)/30/24×Remaining time for annual monthly package |
| Reduce node specifications only / reduce node number / reduce node specifications only and reduce node number |
|
| Improve the node specifications and reduce the number of nodes | First calculate the amount to be paid according to the formula of scenario 1, and then calculate the refund amount according to the formula of scenario 2, summarize these two amounts to obtain the final fee. |
| Reduce the node specification and add the number of nodes | First calculate the refund amount based on the formula of scenario 2, then calculate the reimbursement amount based on the formula of scenario 1, summarize these two amounts to obtain the final fee. |
