Adjusting Public Network Billing
Last updated: 2024-01-08 09:25:40
If the current network billing mode does not meet your business needs, you can choose to adjust the bandwidth or billing mode. For specific operations, refer to Adjusting Network Configuration. This document describes the limitations for adjusting the bandwidth and billing mode, as well as the cost after adjustment.
Adjusting Bandwidth
CVM Billing Mode | Network Billing Mode | Bandwidth Adjustment |
Pay-as-you-go | Bill-by-traffic | Bandwidth can be upgraded or downgraded and takes effects immediately. Costs are settled by traffic, and bandwidth adjustment does not affect cost settlement. |
Monthly subscription | Bill-by-traffic | Bandwidth can be upgraded or downgraded and takes effect immediately. Costs are settled by traffic, and bandwidth adjustment does not affect cost settlement. |
Monthly subscription | Monthly bandwidth | Not supported. |
Changing Billing Mode
CVM Billing Mode | Network Billing Mode | Network Billing Mode Adjustment |
Pay-as-you-go | Bill-by-traffic | Network billing mode cannot be changed. |
Monthly subscription | Bill-by-traffic | It can be switched to pay-as-you-go bandwidth subscription. Each instance can be switched once only. |
| Monthly bandwidth | It can be switched to pay-by-traffic mode. Eeach instance can be switched once only. The used bandwidth is billed at the hourly bandwidth unit price. |
Billing Example
Note:
Only network fees are calculated. Fees for CVM and other devices need to be settled separately.
Adjusting Bandwidth
Upgrading and Downgrading Bill-by-Traffic Bandwidth Value
The bill-by-traffic host bandwidth cap can be upgraded or downgraded at any time. Bandwidth cap adjustment does not affect public network costs, which are billed based on the actual traffic used.
Adjusting the Public Network Billing Mode
Switching from "Monthly Bandwidth Billing" to "Billing by Traffic" for Monthly Subscription Instances
CVM instances are billed in the monthly subscription mode. CVM networks billed in the monthly bandwidth subcription mode can be switched to billing by traffic. Each CVM can only be switched once only. After switchover, the refund amount = Purchased Monthly Bandwidth Cost - Resource Usage Cost.
Resource Usage Cost: If the CVM has been used for a full month, the deduction is based on the monthly bandwidth billing rate. In the case of less than a full month, the deduction is based on the hourly bandwidth billing rate for the duration used, calculated to the second.
Cash coupons used for purchasing are not refundable. Non-coupon fees are refunded to the payer's Tencent Cloud account according to the payment method (cash/bonus) and payment ratio.
For example, on June 1, 2020, at 00:00, you purchased a 2 Mbps monthly bandwidth package for a CVM in the Guangzhou region, costing $6.8 per month, for 3 months. On July 2, 2020, at 12:00 (having used it for 1 month and 36 hours), you switched the 2 Mbps monthly bandwidth package to billing by traffic.
Purchased monthly bandwidth cost = $6.8 × 3 = $20.4.
Resource Usage Cost = $6.8 + $0.0058 x 2 × 36 = $7.2176.
Refund for network switchover = $20.4 - $7.2176 = $13.1824.
Note:
For the resource usage cost, if resourses are used for a full month, it is calculated at the monthly price. In the case of less than a month, it is calculated based on the prorated hourly bandwidth price:
≤ 5Mbps: $0.0058 USD/Mbps/Hour.
> 5Mbps: $0.0208 USD/Mbps/Hour.
For the resource usage cost, $6.8 is the monthly bandwidth fee for a full month. $0.0058 USD/Mbps/Hour × 2 Mbps × 36 hours is the hourly bandwidth cost for less than a full month.
Switching from "Monthly Bandwidth Billing" to "Billing by Traffic" for Monthly Subscription Instances
CVM instances billed annually or monthly can switch their network billing mode from billing by traffic to monthly bandwidth billing. Traffic costs will be billed hourly at the time of conversion; afterwards, the bandwidth cost will be calculated based on the monthly bandwidth billing mode. Each CVM can only be converted once.
Note:
Annual and monthly subscription instances can switch from billing by traffic to monthly bandwidth billing. The default duration for public networks is the remaining duration of the instance, rounded to days and billed proportionally by days (i.e., remaining days / 30 days).
For example, on June 1, 2020, you purchased a 3-month annual and monthly subscription CVM in the Guangzhou region, along with 2Mbps traffic-billed public bandwidth. On July 2, 2020 (with 61 days remaining), you convert the 2Mbps traffic-billed bandwidth to monthly bandwidth, which costs $6.8 per month.
Remaining days proportion = (30 + 31) / 30 = 2.033.
Conversion fee = 6.8 × 2.033 = $13.8244.
