More Traffic (Outbound or Inbound) Billing

Billing is based on whichever is more, outbound or inbound traffic during the usage period.

Application Scenarios

This billing option is suitable for scenarios where traffic fluctuates greatly or bursts in a short term, such as e-commerce flash sales.

Constraints

To use the more traffic (outbound or inbound) billing, the following requirements must be met:

  • A shared bandwidth is required.
  • The minimum bandwidth is 5 Mbit/s, and the maximum bandwidth is 2,000 Mbit/s.

Billing Items

You are billed based on whichever is more, outbound or inbound traffic.

Billed Usage Period

The billed usage period and billing cycle of the more traffic (outbound or inbound) billing are both 1 hour. If your usage duration is less than one hour in a billed usage period, you will be billed for one hour.

For example, if you created a shared bandwidth billed by more traffic at 9:15:00 and deleted the bandwidth at 10:25:00, two bills would be generated.

  • One bill is from 9:15:00 to 10:00:00.
  • The other is from 10:00:00 to 10:25:00.

Billing

In each billed usage period, you are billed for either the inbound or outbound traffic of a shared bandwidth, whichever is more.

For example, if a shared bandwidth has 10 GB of outbound traffic and 20 GB of inbound traffic during the billed usage period from 9:15:00 to 10:00:00, it will be billed by the inbound traffic (20 GB).

Billing Examples

Billing by traffic

Suppose you purchased an EIP billed by traffic on April 18, 2023, 08:45:00 and bound the EIP to an instance on April 18, 2023, 09:45:00. There was 1300 GB traffic generated from 20:00:00 on April 18, 2023 to 06:00:00 on April 19, 2023. Then, you unbound the EIP from the instance on April 19, 2023, 06:45:00 and released the EIP on April 19, 2023, 08:55:00. The EIP reservation price is $0.005 USD per hour, and the traffic price is $0.081 USD per GB. The following table lists the generated expenditures.

60 minutes with 0 GB traffic used

2023/04/18 08:45:00 - 2023/04/18 09:45:00
  • EIP reservation price: 60/60 x 0.005 = 0.005
  • Traffic price: 0

Total price on April 18, 2023: 0.005 + 0 + 0 + 0 + 0 + 64.8 = 64.805

Used traffic: 0 GB

2023/04/18 9:45:00 - 2023/04/18 20:00:00
  • EIP reservation price: 0
  • Traffic price: 0

Used traffic: 800 GB

2023/04/18 20:00:00 - 2023/04/19 00:00:00
  • EIP reservation price: 0
  • Traffic price: 0.081 x 800 = 64.8

2023/04/19

Used traffic: 500 GB

2023/04/19 00:00:00 - 2023/04/19 06:00:00
  • EIP reservation price: 0
  • Traffic price: 0.081 x 500 = 40.5

Total price on April 19, 2023: 0 + 40.5 + 0 + 0 + 0.0108 + 0 = 40.5108

Used traffic: 0 GB

2023/04/19 06:00:00 - 2023/04/19 06:45:00
  • EIP reservation price: 0
  • Traffic price: 0

130 minutes with 0 GB traffic used

2023/04/19 06:45:00 - 2023/04/19 08:55:00
  • EIP reservation price: 130/60 x 0.005 = 0.0108
  • Traffic price: 0
  • The prices are just examples. The actual prices are those displayed on EIP Pricing Details.
  • If an EIP billed by traffic uses a dedicated bandwidth, only the bandwidth used in the outbound direction will be billed.

Price Change After Specification Change

If you change the specifications of a shared bandwidth billed by more traffic (outbound or inbound), the original order will become invalid and a new order will be placed. You will be billed based on the new specifications.

If you change specifications within an hour, multiple billing records will be generated. The start time and end time of each billing record correspond to the effective time of different specifications within the hour.

For example, if you purchased a shared bandwidth (500 Mbit/s) billed by more traffic (outbound or inbound) at 09:00:00 and increased the bandwidth to 1,000 Mbit/s at 09:30:00, the following items would be billed:

  • Bandwidth of 500 Mbit/s from 09:00:00 to 09:30:00
  • Bandwidth of 1,000 Mbit/s from 09:30:00 to 10:00:00

Arrears Impact

Figure 1 shows the statuses an EIP billed by more traffic (outbound or inbound) can have throughout its lifecycle. After an EIP billed by more traffic (outbound or inbound) is purchased, it enters the valid period and runs normally during this period. If your account goes into arrears, the resource enters a grace period and then a retention period.

Arrears Reminder

The system will bill you for pay-per-use resources after each billing cycle ends. If your account goes into arrears, we will notify you by email, SMS, or in-app message.

Impact of Arrears

If your account is insufficient to pay your amount due, your account goes into arrears and the pay-per-use resources enters 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 status turns to Frozen and enters a retention period. You cannot perform any operations on them.

If you do not bring your account balance current before the retention period ends, the yearly/monthly resource will be released.
