This topic describes the billing rules for and pricing of the database proxy feature in ApsaraDB RDS for PostgreSQL. The database proxies include general-purpose and dedicated database proxies.
Database proxy instances, read-only RDS instances, and primary RDS instances are separately billed.
If your primary RDS instance is locked, the database proxies that are enabled for the primary RDS instance are not released but can process only read requests.
If your primary RDS instance is released, the database proxies that are enabled for the primary RDS instance are automatically released. You are no longer charged for the database proxies.
If your RDS instance resides in Hangzhou Zone C or Hangzhou Zone D, database proxies cannot be enabled for the RDS instance. If you want to enable database proxies for the RDS instance, you must migrate the RDS instance from Hangzhou Zone C or Hangzhou Zone D to another zone. For more information, see Migrate an ApsaraDB RDS for PostgreSQL instance across zones in the same region.
To view the details of a database proxy, perform the following operations: Log on to the ActionTrail console, go to the Advanced Event Query page, and then find the event whose Resource Type is acs::rds::dbproxy. The details include the time when the database proxy is enabled, the operator who enables the database proxy, and the IP address of the operator.
To disable database proxies, follow the instructions provided in Disable the database proxy feature.
