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

    Last Updated:Mar 28, 2026

    This page lists primary instance specifications for ApsaraDB RDS for MySQL Standard Edition (formerly X86), covering all current editions and phased-out types.

    For differences between the Yitian Edition and Standard Edition, see Product types.
    The purchase page shows which instance types are available in your region. Some types listed here may not be available in all regions.
    Serverless ApsaraDB RDS for MySQL instances measure resources in RDS Capacity Units (RCUs) rather than CPU and memory. For compatibility, they carry the following specification codes: mysql.n2.serverless.1c (Basic Edition) and mysql.n2.serverless.2c (High-availability Edition).
    Some instance types no longer support standard SSDs. For details, see [Discontinuation/Decommission] Starting July 1, 2022, some RDS instances will no longer support standard SSDs.
    Maximum connections is the maximum number of processes that can connect to an instance simultaneously.
    ApsaraDB RDS for MySQL does not support public bandwidth adjustments.

    Phased-out instance types

    The following instance types are no longer available for new instances. If your existing instance uses a phased-out type, upgrade it to a current type — phased-out types do not support new features, and you cannot generate orders (such as storage capacity changes) for them. To upgrade, see Change instance configurations.
