Pay-per-Use Billing

Application Scenarios

Pay-per-use is suitable for applications or services that cannot be interrupted when facing temporary or sudden traffic increases or unpredictable demands, such as e-commerce flash sales, testing, and scientific computing.

Billed Items

• For each peering connection attachments, you will only be charged for the attachment. The traffic cost is included in your global private bandwidth. For details about how global private bandwidths are billed, see Central Network Billing Items.
• CFW instance attachments and the traffic used by the attachments are free.

Billed Usage Period

• Each attachment is billed hourly and only in full hours. If the duration is less than one hour, the attachment is still billed for a full hour. The following uses a VPC attachment as an example.
  • Scenario 1: You created a VPC attachment to an enterprise router at 12:36 on July 6, 2022 and deleted the attachment at 12:57 on July 6, 2022. In this case, you need to pay for a full hour.
  • Scenario 2: You created a VPC attachment to an enterprise router at 12:59 on July 6, 2022 and deleted the attachment at 13:01 on July 6, 2022. In this case, your usage spanned 2 clock hours, so you need to pay for 2 full hours.
• The inbound traffic that flows from each attachment to the enterprise router is billed.

Billing Example

The enterprise router is free. You are billed for how long each attachment is used and the traffic each attachment uses to communicate with the enterprise router.

In this example, each attachment costs $0.06 USD/hour, and the unit price of traffic is $0.02 USD/GB. Figure 1 shows how the total price is calculated, and Table 2 describes the price of each billed item.

Impacts of Arrears

Figure 2 shows the statuses a pay-per-use ECS can have throughout its lifecycle. After an enterprise router is purchased, it enters the valid period and runs normally during this period. If your account goes into arrears, the enterprise router enters a grace period and then a retention period.

Arrears Alert

The system will deduct fees for pay-per-use resources at the end of each billing cycle. If your account goes into arrears, we will notify you by email, SMS, or in-app message.

Impacts of Arrears

If your account is insufficient to pay your amount due, your account goes into arrears, and pay-per-use resources enter the grace period. You are still responsible for expenditures generated during the grace period. You can view the charges on the Billing Center > Overview page and pay any past due balance as needed.

If you do not bring your account balance current before the grace period expires, the resource turns to Frozen and enters a retention period.

If you do not bring your account balance current before the retention period ends, the resources will be released and the data cannot be restored.
