Server Load Balancer:ALB billing overview

Last Updated:Mar 08, 2024

This topic describes the billing methods, billable items, and billing rules for Application Load Balancer (ALB).

Billing methods

Application Load Balancer (ALB) supports the pay-as-you-go and subscription billing methods.

  • Pay-as-you-go: You are charged for the actual usage of each billable item. Fees are deducted after resources are consumed. This billing method is ideal for scenarios in which the usage of resources is difficult to predict.

  • Subscription (resource plans): You purchase resources in advance to offset fees. Resource plans are ideal for scenarios in which the usage of resources is easy to predict.

  • The subscription billing method is more cost-effective than the pay-as-you-go billing method.

  • Resource overages are billed based on the pay-as-you-go billing method and included in the bills. We recommend that you purchase resource plans based on the services that you need and the estimated amount of resource usage. For more information, see Purchase an ALB resource plan.

Billable items

The following figure shows the billable items of an ALB

Billing cycle

ALB instances and Load Balancer Capacity Units (LCUs) are billed on an hourly basis based on resource usage. Bills are generated 1 hour after a billing cycle ends. The time when bills are generated is determined by the system.

You are charged Internet data transfer fees for the elastic IP addresses (EIPs) that are used by an Internet-facing ALB instance to access the Internet. The billing cycle, the time when fees are deducted, and the time when bills are generated are determined by the pay-as-you-go EIPs that are used by the ALB instance. For more information, see Billing cycle.
