This topic describes the billing rules for the dedicated proxy feature of ApsaraDB RDS for MySQL.

Overview of a dedicated proxy

A dedicated proxy serves as the network proxy between a database and an application. The dedicated proxy is used to distribute all read and write requests from the application to the database. If you have a large number of read and write requests, we recommend that you use the read/write splitting feature of a dedicated proxy to forward read and write requests to the primary and read-only instances. This way, the number of requests sent to the primary instance is reduced. For more information about how to enable the read/write splitting feature, see Enable and configure the dedicated proxy feature for an ApsaraDB RDS for MySQL instance.

Precautions

  • Proxy instances, read-only RDS instances, and primary RDS instances are separately billed.
  • If the primary RDS instance is released, the enabled proxy instances are automatically released. You are no longer charged for the dedicated proxy feature.

Billing

You are charged for the usage of the dedicated proxy feature. When you enable the dedicated proxy feature in the ApsaraDB RDS console, the system prompts you to view the billing rules. If you enable the feature, Alibaba Cloud considers that you acknowledge and agree to the billing rules. For more information about how to enable the dedicated proxy feature, see Enable and configure the dedicated proxy feature for an ApsaraDB RDS for MySQL instance.
Note
  • To view the details about the enabling operation, perform the following operations: Log on to the ActionTrail console, go to the Event Detail Query page, and then find the event whose Resource Type is ACS::RDS::DbProxy. The details include the time when the feature is enabled, the user who enables the feature, and the IP address of the user.
  • For more information about how to disable the dedicated proxy feature, see Disable the dedicated proxy feature for an ApsaraDB RDS for MySQL instance.

Billing methods

By default, the dedicated proxy feature is disabled, and no fees are generated. If you enable the dedicated proxy feature, you are charged an hourly fee for the feature based on the pay-as-you-go billing method. Fees are deducted from your account every hour. To check the bills of the dedicated proxy feature, find the billing item whose Billing Item Code is MaxscaleChargedSliceNum on the Details tab.

Note If you upgrade the database proxy of your primary RDS instance from a shared proxy to a dedicated proxy, you can use the dedicated proxy feature free of charge for at least one year. For more information, see Upgrade the database proxy of an ApsaraDB RDS for MySQL instance from a shared proxy to a dedicated proxy.
