Billable items of resources

Resource Billable Item Scenario References
Enterprise Edition transit routers Connections An Enterprise Edition transit router is connected to virtual private clouds (VPCs), virtual border routers (VBRs), or IPsec-VPN connections. Billing rules for Enterprise Edition transit routers
Data forwarding An Enterprise Edition transit router forwards network traffic for VPCs, VBRs, or IPsec-VPN connections.
Inter-region connections Bandwidth plans Enable network communication between network instances in different regions.

To allow network instances in different regions to communicate with each other, you must create inter-region connections between the network instances. Bandwidth resources for inter-region connections can be allocated in the following modes. You can select a mode based on your business requirements.

  • Allocate bandwidth from bandwidth plans

    In this mode, you are charged for bandwidth plans.

  • Pay-by-data-transfer

    In this mode, you are charged for data transfer.

Billing rules for Enterprise Edition transit routers

Billing rules

Billable item Billing rule Billing method Billing cycle
Connections You are charged based on the total number of VPC, VBR, and IPsec-VPN connections on the Enterprise Edition transit router.

Connection fee for an Enterprise Edition transit router = Unit price of the connection (USD/connection/hour) × (The total number of VPC connections + VBR connections + IPsec-VPN connections on the Enterprise Edition transit router) × Usage duration (hours).

The usage duration refers to the total period of time from when the connection is created on the Enterprise Edition transit router to when the connection is closed on the Enterprise Edition transit router.

Pay-as-you-go

A billing method that allows you to use resources and pay for them afterwards. You are billed based on the resources that are consumed.

1 hour

If the usage duration is less than an hour, it is rounded up to 1 hour.

Data forwarding You are charged based on the amount of data transfer from the VPCs, VBRs, and IPsec-VPN connections to the Enterprise Edition transit router.

Data forwarding fee for an Enterprise Edition transit router = Unit price of data forwarding (USD/GB) × (The total amount of data transfer from the VPCs, VBRs, and IPsec-VPN connections to the Enterprise Edition transit router).

Data transfer from the Enterprise Edition transit router to the VPCs, VBRs, and IPsec-VPN connections is free of charge.

Billing rules for inter-region connections

Billing rules

Billable Item Billing rule Billing method Billing cycle
Bandwidth plans To allow network instances in different regions to communicate with each other, you must create inter-region connections between the network instances. Bandwidth resources for inter-region connections can be allocated in the following modes. You can select a mode based on your business requirements.

The billing rules for the allocation modes are:

  • Allocate bandwidth from bandwidth plans

    Before you can create an inter-region connection, you must purchase a bandwidth plan and allocate bandwidth resources from the bandwidth plan to the inter-region connection. Each bandwidth plan is billed for its maximum bandwidth value.

    Fee of a bandwidth plan = Unit price of bandwidth ((USD/month for every Mbit/s) × Maximum bandwidth value (Mbit/s) × Subscription duration (months).

  • Pay-by-data-transfer

    For more information about pay-by-data-transfer, see What is CDT?

Subscription

A billing method that allows you to subscribe to bandwidth plans on a monthly or annual basis. Fees must be paid before resources can be consumed.

1 month
Data transfer Pay-as-you-go

A billing method that allows you to use resources and pay for them afterwards. You are billed based on the resources that are consumed.

Pricing of bandwidth

The following table describes the prices of bandwidth within the Chinese mainland. For more information about the pricing of bandwidth in other areas,visit the buy page. For more information about the pricing of data transfer, see Cross-region data transfers.

Bandwidth is billed based on a tiered pricing model. For example, Alice purchased a bandwidth plan that supports network communication within the Chinese mainland. The maximum bandwidth value of the bandwidth plan is 110 Mbit/s, and the subscription duration is one month. The fee for the bandwidth plan is:

USD 34/month for every Mbit/s × 100 Mbit/s × 1 (month) + USD 13/month for every Mbit/s × 10 Mbit/s × 1 (month) = USD 3,530

Billing examples

The following examples show the billing rules for CEN.

Billing example

A company attached VPC1, VPC2, VBR1, VBR2, and IPsec-VPN Connection 1 to a CEN instance. The IPsec-VPN connection is an Internet connection. The company also purchased Bandwidth Plan 1 for network communication within the Chinese mainland. The maximum bandwidth of Bandwidth Plan 1 is 160 Mbit/s, and the subscription duration is one month. Bandwidth resources for Inter-region Connection 1, Inter-region Connection 2, and Inter-region Connection 3 are allocated from Bandwidth Plan 1. Network communication among the network instances attached to the CEN instance is established.

The following table describes the resources consumed by each network instance and inter-region connection in June 2022 (30 calendar days).

Table 1. Resources consumed by the network instances and connections
Network instance/connection Total duration of connection to Enterprise Edition transit router Total data transfer to Enterprise Edition transit router
VPC1 24 hours/day × 30 days = 720 hours 20 GB of data transfer to the Enterprise Edition transit router in China (Hangzhou)
VPC2 24 hours/day × 30 days = 720 hours 20 GB of data transfer to the Enterprise Edition transit router in China (Shenzhen)
VBR1 24 hours/day × 30 days = 720 hours 30 GB of data transfer to the Enterprise Edition transit router in China (Hangzhou)
VBR2 24 hours/day × 30 days = 720 hours 30 GB of data transfer to the Enterprise Edition transit router in China (Qingdao)
IPse-VPN Connection 1 24 hours/day × 30 days = 720 hours 40 GB of data transfer to the Enterprise Edition transit router in China (Qingdao)
