Amazon Relational Database Service Proxy pricing

Amazon RDS Proxy is priced based on the capacity of undeerlying instances. For provisioned instances on Amazon Aurora, Amazon Relational Database Service (Amazon RDS) for MariaDB, Amazon Relational Database Service (Amazon RDS) for MySQL, and Amazon Relational Database Service (Amazon RDS) for PostgreSQL, Amazon RDS Proxy is priced per vCPU per hour. For Amazon Aurora Serverless v2, Amazon RDS Proxy is priced per Aurora Capacity Unit (ACU) per hour consumed by your database.

Partial hours are billed in 1-second increments with a 10-minute minimum charge following a billable status change such as creating, starting, or modifying.

There are no additional charges associated with the default endpoint you get when you create an Amazon RDS Proxy. You can also add read-only or read-write proxy endpoints, each with their own VPC settings. Adding an Amazon RDS Proxy endpoint provisions an AWS PrivateLink interface endpoint, which incurs additional charges as described on the PrivateLink pricing page.
