If the billing method of network usage of an Elastic Compute Service (ECS) instance that uses a public IP address does not meet your business requirements, you can change the billing method.

Prerequisites

Before you change the billing method of network usage of a subscription instance from pay-by-bandwidth to pay-by-traffic, make sure that your account has the permission to perform the configuration downgrades.
Note You can click Privileges & Quotas on the Overview page in the ECS console to go to the Privileges & Quota Management page, and then check whether your account has the permission to perform configuration downgrades.

Background information

The billing methods available for network usage are pay-by-bandwidth and pay-by-traffic. You can change the billing method based on your needs.

This topic describes how to change the billing method of network usage of an instance that uses a public IP address.

Change from pay-by-bandwidth to pay-by-traffic

The following section describes how to change the billing method of network usage of an instance from pay-by-bandwidth to pay-by-traffic.
  1. Log on to the ECS console.
  2. In the left-side navigation pane, choose Instances & Images > Instances.
  3. In the top navigation bar, select a region.
  4. Find the instance for which you want to change the billing method of network usage. Then, perform a proper operation to go to the configuration page based on the billing method of the instance.
    • Subscription

      Find the subscription instance for which you want to change the billing method of network usage. Click Upgrade/Downgrade in the corresponding Actions column. In the Upgrade/Downgrade Wizard dialog box, select Downgrade > Bandwidth Configuration and then click Continue.

      Notice If you have performed a temporary bandwidth upgrade, changing the billing method from pay-by-bandwidth to pay-by-traffic will cancel all temporary bandwidth upgrade orders including the ones in effect and pending ones for the instance. You will be refunded for canceled temporary bandwidth upgrade orders.
    • Pay-as-you-go
      • Change the billing method of a single instance: Find the pay-as-you-go instance for which you want to change the billing method for network usage. Choose More > Configuration Change > Change Pay-as-you-go Instance Bandwidth in the corresponding Actions column.
      • Change the billing method of multiple instances: Select the pay-as-you-go instances for which you want to change the billing method of network usage. In the lower part of the page, choose More > Configuration Change > Change Pay-as-you-go Instance Bandwidth.
  5. Find the Bandwidth section, select Pay-By-Traffic, and then set a peak bandwidth value.
  6. Read the notes and terms of service. Select ECS Service Terms.
  7. Confirm the configuration costs, click Confirm in the lower part of the page, and then perform the subsequent operations as instructed on the page.
    The new configurations take effect immediately after you change the billing method.
