ApsaraDB RDS for PostgreSQL supports two database proxy types: general-purpose and dedicated. General-purpose proxies are free. Dedicated proxies are billed on a pay-as-you-go basis.
Usage notes
Database proxy instances, read-only instances, and primary instances are billed separately.
Primary instance locked: The proxy is not released but can process only read requests.
Primary instance released: The proxy is automatically released. Billing stops.
Database proxies cannot be enabled for instances in Hangzhou Zone C or Hangzhou Zone D. To use database proxies with these instances, first migrate the instance to another zone.
To audit proxy activity, log in to the ActionTrail console, go to the Advanced Event Query page, and filter by Resource Type = acs::rds::dbproxy. The results show when the proxy was enabled, who enabled it, and the operator's IP address.
General-purpose proxies (no charge)
General-purpose proxies are free.
Dedicated proxies (pay-as-you-go)
Dedicated proxies are billed at an hourly rate. When you enable a dedicated proxy in the ApsaraDB RDS console, the billing rules are displayed for your review. Enabling the proxy constitutes acceptance of those rules.
To switch between proxy types, see Change the database proxy type and Database proxy types.
Billing method
Dedicated proxies use pay-as-you-go billing. Fees are calculated and deducted once per hour.
To view charges for dedicated proxies:
Go to the Bill DetailsBilling ItemDatabase Proxy Instance Shards page.
