Yearly/Monthly Billing

Application Scenarios

In yearly/monthly billing mode, you need to pay for a required duration in advance. This mode is suitable for long-term and relatively fixed service requirements. The yearly/monthly billing mode is recommended for the following scenarios:

• Stable services: enterprise websites, online malls, blogs, and others. Yearly/Monthly billing provides higher cost efficiency.
• Long-term projects: scientific research projects, large-scale events, and others. Yearly/Monthly billing facilitates stable supply of resources throughout the project.
• Service peak estimation: e-commerce promotion season, festivals, holidays, and others. Resources insufficiency can be avoided by pre-purchasing resources for peak demands.
• High data security: For services that require high data security, yearly/monthly billing facilitates continuous usage of the resources.

Billing Items

Service version, database extension package, and OBS extension package.

Billing Period

The billing period of yearly/monthly DSC is determined by the purchased duration (UTC+8). The billing period starts from the time you activate or renew your subscription (precise to seconds), and ends at 23:59:59 on the expiration date.

For example, if you purchased a DSC instance for one month on Mar 08, 2023, 15:50:04, the billing period is from Mar 08, 2023, 15:50:04 to Apr 08, 2023, 23:59:59.

Billing Examples

If you purchase a DSC professional edition instance at 2023/03/08 15:50:04 and purchase a database expansion package and an OBS expansion package. The subscription is for one month, and you manually renew it for one month before it expires:

• The first billing period: Mar 08, 2023, 15:50:04–Apr 08, 2023, 23:59:59
• The second billing period: Apr 08, 2023, 23:59:59–May 08, 2023, 23:59:59

Impact on Billing After Specification Change

If the specifications of your purchased yearly/monthly DSC instance do not meet your service requirements, you can change the specifications on the DSC console or upgrade or downgrade the DSC edition, you can also add or unsubscribe from unnecessary database and OBS expansion packages.

Edition upgrade or expansion package quantity increase: You need to pay for the price difference.

Currently, DSC does not support downgrade. If you want to use DSC of a low-specification edition after the upgrade, unsubscribe from DSC and purchase again.

Specification upgrade fee = New edition price × Remaining period - Old specification price × Remaining period

The remaining period in the formula is the remaining days of each calendar month divided by the maximum days of corresponding calendar month. For more information, see Pricing of a Changed Specification.

Impacts of Expiration

Figure 2 describes the status of each stage of a yearly/monthly DSC instance. After a DSC instance is purchased, it enters the valid period and runs normally during this period. If the instance is not renewed after it expires, before being deleted, it first enters a grace period and then a retention period.

Expiration Reminder

From the 7th day before a yearly/monthly DSC instance expires, the system will send an expiration reminder to the creator of the account by email, SMS, and internal message.

Impact After Expiration

If the DSC professional edition purchased in yearly/monthly mode expires and is not renewed, the DSC enters the grace period. During the grace period, you can view historical task data but cannot add or edit tasks.

If you do not renew your yearly/monthly DSC instance before the grace period ends, it goes into the retention period and its status turns to Frozen. You cannot perform any operations on such instances in the retention period.

For details, see Retention Period.

After the retention period expires, if the yearly/monthly DSC is not renewed, resources in DSC will be deleted and cannot be restored.
