2. If you have purchased a monthly or yearly subscription CVM, you can configure the following settings:
Option | Note |
Unify Expiry Date | Unified expiry date allows users to synchronize the expiration time of prepaid devices to the same date each month, making it convenient for users to manage and renew their cloud servers uniformly. If you have never used the Unified Expiration Date feature, the purchase page will not display the checkbox for it. To set up this feature, please refer to the Unified Expiration Date operation guide. If you have used the Unified Expiration Date feature before, the purchase page will display a checkbox for it. When purchasing a CVM with this option selected, the duration must be longer than one month. For any partial month, the system will calculate the fees based on the monthly price converted to daily rates. For example, if you purchase a CVM on November 12th with a unified expiry date and a monthly price of 60 RMB/month, and the unified expiry date is the 20th of each month, the CVM will expire on December 20th. The amount you need to pay is 76 RMB (60 + 60 ÷ 30 × 8). |
Auto-Renewal | For Monthly Subscription CVM instances only.
Select Auto-renew the device monthly upon expiration if your account has sufficient balance to avoid manual renewal when the device expires. |
