Yearly/Monthly
If you expect to use resources for a longer period, you can save money by selecting yearly/monthly billing. You can pre-purchase cloud service resources at discounted prices. This section describes the billing rules for yearly/monthly MAS instances.
Application Scenarios
If you want to ensure resource stability over a certain period of time, yearly/monthly billing is a good choice for the following types of workloads:
- Running for a long time with constant resources: For example, enterprise official websites, online malls, and blogs. Yearly/Monthly billing provides higher cost-efficiency.
- Long-term: For example, scientific research projects and large-scale events. Yearly/Monthly billing ensures stable resource supply throughout the project period.
- Predictable service peaks: For example, e-commerce promotions, festivals, and holidays. Resource insufficiency can be avoided by purchasing resources in advance for peak demands.
- High data security: For services that require high data security, yearly/monthly billing facilitates continuous usage of the resources.
Billing Cycle
The billing period of yearly/monthly MAS instances is determined by purchase duration (UTC+8). The billing starts when you activated or renewed the subscription (precise to seconds), and ends at 23:59:59 of the expiry date.
For example, if you purchased a MAS instance for one month at 15:50:04 on Oct 16, 2023, the billing period is from Oct 16, 2023, 15:50:04 to Nov 16, 2023, 23:59:59.
Billing Example
Assume that you purchased a yearly/monthly MAS instance for one month at 15:50:04 on Oct 16, 2023, and will manually renew it for another month before it expires:
- The first billing period: Oct 16, 2023, 15:50:04 to Nov 16, 2023, 23:59:59
- The second billing period: Nov 16, 2023, 23:59:59 to Dec 16, 2023, 23:59:59
You need to pay for each billing period in advance. The billing formula is as follows: Unit price of instance specifications x Purchased duration.
For example, if the monthly price of the instance is USD2000, the total fee for the preceding two billing periods is 2000 x 2 = USD4000.
Impact of Expiration
Figure 1 describes the status of each stage of a yearly/monthly MAS instance. After you purchase an instance, it runs properly during the billing period, which is also called "validity period". If the instance is not renewed in time, it goes into the grace period and then the retention period.
Expiration reminder
From the 7th day before a yearly/monthly MAS instance expires, the system will send an expiration reminder through the email address or mobile number you used to create your Huawei Cloud account or through internal messages.
Impact after expiration
If your yearly/monthly MAS resource is not renewed, it goes into the grace period and changes to the Expired state. You can still view the instance during this period.
If you do not renew your yearly/monthly MAS instance before the grace period ends, it goes into the retention period and its status turns to Frozen. You cannot perform any operations on your yearly/monthly MAS instance in the retention period.
If you still do not renew your yearly/monthly MAS instance before the retention period ends, the instance will be released, and the data cannot be restored.
