ApsaraDB RDS:RDS MySQL Standard Edition (formerly X86) primary instance specifications

Last Updated:Mar 03, 2026

This topic describes the primary instance specifications for RDS MySQL Standard Edition (formerly X86). It includes information about the latest and legacy specifications to help you understand the configuration of each instance type.

Note
  • For more information about the differences between the Yitian Edition and Standard Edition, see Product types.

  • Some instance types in this list may be discontinued. The purchase page displays the instance types that are currently available.

  • Serverless ApsaraDB RDS for MySQL instances use RDS Capacity Units (RCUs) to measure resources and do not have traditional CPU and memory specifications. However, to maintain compatibility with existing processes, they are assigned the following specification codes: mysql.n2.serverless.1c for the Basic Edition and mysql.n2.serverless.2c for the High-availability Edition.

  • Some RDS instances in this list no longer support standard SSDs. Higher-performance ESSDs are available instead. For more information, see [Discontinuation/Decommission] Starting July 1, 2022, some RDS instances will no longer support standard SSDs.

  • The maximum connections listed indicates the maximum number of processes that can connect to an RDS for MySQL instance simultaneously.

  • If you cannot select a target instance type when you change specifications, it may be because supported instance types vary by region. The purchase page shows the available instance types.

  • RDS for MySQL does not support public bandwidth adjustments.

ApsaraDB RDS for MySQL Basic Edition (with cloud disks)

Important
  • Actual maximum IOPS: The actual maximum input/output operations per second (IOPS) depends on the storage class, storage space, and instance type. For more information, see Maximum IOPS formula.

  • Actual maximum throughput: The actual maximum throughput depends on the storage class, storage space, and instance type. For more information, see Maximum throughput formula.

Phased-out ApsaraDB RDS for MySQL instance types

The following table lists phased-out ApsaraDB RDS for MySQL instance types. When you create an RDS instance, you cannot select a phased-out instance type. You can upgrade phased-out instance types to some available instance types. You cannot generate an order for an RDS instance that uses a phased-out instance type. For example, you cannot generate an order to change the storage capacity of an RDS instance that uses a phased-out instance type. We recommend that you use the most recent instance type. For more information about how to change the storage capacity of an RDS instance, see Change instance configurations.

Note

Phased-out instance types cannot support some new features. We recommend that you upgrade a phased-out instance type to the most recent instance type.
