Billing Items (Dedicated Load Balancers)

Billing

You will be charged for how many LCUs you use and how long a load balancer is retained in your account, as described in Table 1.

For details about the pricing, see ELB Price Calculator. Resources may vary depend on regions. The actual prices are subject to those displayed on the ELB console.

The billing items of dedicated load balancers vary by specification type. For details, see Table 2.

NOTE:

• √ indicates that the billing item is involved. × indicates that the billing item is not involved.
• If you bind an EIP to a load balancer, you will also be charged for the EIP and the bandwidth used by the EIP.

  For details about EIP pricing, see Elastic IP Pricing Details.

Constraints

Elastic specifications are available in CN Southwest-Guiyang1, CN East-Shanghai1, CN-Hong Kong, and AP-Singapore. They will soon be available in other regions.

LCU Pricing

An LCU measures the dimensions on which a dedicated load balancer routes the traffic. See LCU price in Table 3.

The unit price of LCU varies depending on the specifications. See the actual price of LCU on the console. LCU price (USD) = Unit price x Number of LCUs x Required duration.

NOTE:

• If you deploy a dedicated load balancer in multiple AZs, its performance will multiply as the number of AZs increases. For details about AZs, see Region and AZ.
• Note the following when calculating the number of LCUs:
  • LCU quantity refers to the number of LCUs corresponding to a specification in a single AZ. For details, see LCU Billing for Fixed Specifications.
  • If you select multiple AZs for a load balancer, the number of LCUs is calculated as follows: Number of LCUs = LCUs of the selected specification x Number of the selected AZs.

LCU Billing for Elastic Specifications

An LCU has four dimensions: new connections, maximum concurrent connections, processed traffic, and rule evaluations.

You can calculate the number of LCUs by taking the maximum LCUs consumed across the four dimensions.

Table 5 lists the LCU performance supported by different protocols.

Billing Examples

A pricing example for a network load balancer

Assume your network load balancer establishes 1,000 new TCP connections per second, each lasting for three minutes, and the traffic processed by your load balancer is 1,000 KB per second.

The unit price of LCU in the current region is $0.00833 USD/hour. The LCU price is calculated as the table shown below.

In this example, the traffic dimension consumes the most LCUs (3.6 LCUs). So the LCU price is calculated based on the LCUs consumed by the processed traffic.

The total LCU price for using this network load balancer for 2 hours is calculated as follows:

LCU price = Unit price x Number of LCUs x Required duration = $0.00833 USD/hour x 3.6 LCUs x 2 hours =$0.059976 USD

A pricing example for an application load balancer

Assume your application load balancer establishes 1,000 new HTTP/HTTPS connections per second, each lasting for three minutes. A client sends an average of 400 requests per second and the traffic processed by this load balancer is 1,000 KB per second. You have configured 20 forwarding rules for your load balancer to route requests.

The unit price of LCU in the current region is $0.00833 USD/hour. The LCU price is calculated as the table shown below.

In this example, the maximum concurrent dimension consumes the most LCUs (60 LCUs). So the LCU price is calculated based on the LCUs consumed by the maximum concurrent connections.

The total LCU price for using this application load balancer for 2 hours is calculated as follows:

LCU price = Unit price x Number of LCUs x Required duration = $0.00833 USD/hour x 60 LCUs x 2 hours = $0.9996 USD

LCU Billing for Fixed Specifications

You are charged for the LCUs based on each fixed specification you select. You can select either application load balancing (HTTP/HTTPS) or network load balancing (TCP/UDP), or both.
