This topic describes the billing rules for the dedicated proxy feature of ApsaraDB RDS for MySQL.
- Proxy instances, read-only RDS instances, and primary RDS instances are separately billed.
From January 15, 2020 to August 31, 2020, one proxy instance was provided free of charge. If you enable more than one proxy instance, you are charged additional fees.
Since September 1, 2020, you must pay for every proxy instance that is enabled. The enabled proxy instances are charged at an hourly rate on a pay-as-you-go basis. A maximum of 60 proxy instances can be created for each RDS instance. These proxy instances provide higher processing capabilities. A SysBench test shows that each proxy instance supports 20,000 to 50,000 queries per second (QPS) in online transaction processing (OLTP) scenarios. We recommend that you estimate the maximum QPS that is supported by your RDS instance based on your actual stress test results.
Proxy instances support only the pay-as-you-go billing method. The following table lists the prices of proxy instances in different Alibaba Cloud regions.
