Billing of basic services

Scenarios

Billing rules

Suitable for users whose traffic curve fluctuates significantly, has bandwidth spikes, and has an all-day bandwidth utilization of less than 30%.

• Description: billed in tiers based on the actual data transfer that flows out of Alibaba Cloud CDN points of presence (POPs) each month.

• Billable item: data transfer.

• Payment method: pay-as-you-go or upfront resource plan.

• Billing cycle: Settled by hour. Bills are usually generated about 3 to 4 hours after the current billing cycle ends. The actual bill generation time is subject to the system.

Scenarios

Billing rules

Suitable for users whose traffic curve is relatively stable and whose all-day bandwidth utilization is greater than 30%.

• Description: billed based on the daily peak bandwidth. A bandwidth value is sampled every 5 minutes, which produces 288 values per day. The maximum value is used.

• Billable item: peak bandwidth.

• Payment method: pay-as-you-go.

• Billing cycle: billed by day. The bill of the previous day is generated and the fee is deducted after 00:00 each day. The actual bill generation time is subject to the system.

Scenarios

Billing rules

Suitable for users whose data transfer volume is large and whose traffic peaks are unpredictable, or whose monthly spending exceeds CNY 100,000.

• Description: the downstream bandwidth sampled every 5 minutes is used as a metering point. There are 288 ((60/5) * 24) metering points per day, and the number of metering points per month is N = 288 * (the number of billable days in the month). All metering points are sorted in descending order of bandwidth, and M points are deducted starting from the largest bandwidth (M = N * 0.05; if the result contains a decimal, the decimal part is removed and the value is rounded down to an integer). The bandwidth value of the (M + 1)th point is the 95th percentile billable bandwidth of the month.

  • Example 1: March has 31 days, so the total number of billable points is 288 * 31 = 8,928. After the 8,928 points are sorted in descending order of bandwidth, the number of deducted points is 8,928 * 0.05 = 446.4. Removing the decimal part gives 446, so the 447th point is the 95th percentile bandwidth of the month.

  • Example 2: April has 30 days, so the total number of billable points is 288 * 30 = 8,640. After the 8,640 points are sorted in descending order of bandwidth, the number of deducted points is 8,640 * 0.05 = 432, so the 433rd point is the 95th percentile bandwidth of the month.

  • Example 3: If February has 29 days, the total number of billable points is 288 * 29 = 8,352. After the 8,352 points are sorted in descending order of bandwidth, the number of deducted points is 8,352 * 0.05 = 417.6. Removing the decimal part gives 417, so the 418th point is the 95th percentile bandwidth of the month.

  • Example 4: If February has 28 days, the total number of billable points is 288 * 28 = 8,064. After the 8,064 points are sorted in descending order of bandwidth, the number of deducted points is 8,064 * 0.05 = 403.2. Removing the decimal part gives 403, so the 404th point is the 95th percentile bandwidth of the month.

• Billable item: monthly 95th percentile peak bandwidth.

• Payment method: pay-as-you-go.

• Calculation method:

  • The final fee is the sum of the monthly 95th percentile bandwidth fees of all regions.

  • The monthly 95th percentile bandwidth fee of a region = the monthly 95th percentile bandwidth value of the region × the monthly 95th percentile bandwidth unit price of the region × the effective factor.

    Note

    • Effective factor: effective factor = the number of effective days in the month / the total number of days in the month. For example, in April 2021, the total number of days in the month is 30 and the number of effective days in the billing period is 26, so the effective factor is 26 ÷ 30 = 0.86666667.

    • Effective days: the number of days from the effective date of the 95th percentile billing to the end of the month. For example, if 2021-04-05 is the effective date of the 95th percentile billing, the number of effective days in April 2021 is 26.

• Billing cycle: in the early morning of the first day of the calendar month after the current billing cycle ends.

  For example, on March 1, 2021, the bill of the complete month of February (from 2021-02-01 00:00:00 to 2021-02-28 23:59:59) is generated.

  Note

  • After a bill is generated, the corresponding fee is automatically deducted from your account balance to settle the bill. Make sure that your account balance is sufficient at settlement to avoid Alibaba Cloud CDN service suspension caused by overdue payments. For details about the overdue payment rules, see Overdue payments.
