ApsaraDB RDS:Instance types for standard primary ApsaraDB RDS for MySQL instances (original x86 architecture)

Last Updated:Aug 27, 2025

This topic provides an overview of instance types for standard primary ApsaraDB RDS for MySQL instances that originally use the x86 architecture. This overview includes the most recent instance types, the phased-out instance types, and the specifications for each instance type.

Note
  • For more information about the differences between standard and YiTian product types, see Product types.

  • Some instance types may no longer be available. You can select only the instance types that are available on the ApsaraDB RDS buy page.

  • The resources of RDS for MySQL Serverless instances are measured by RCUs instead of CPU cores and memory. However, the instance type codes of these instances keep the same format as other RDS instances to avoid compatibility issues. The instance type codes for RDS for MySQL Serverless instances include mysql.n2.serverless.1c (instances running Basic Edition) and mysql.n2.serverless.2c (instances running High-availability Edition).

  • The standard SSD storage type is no longer available for purchase for some RDS instances. You can select the Enterprise SSD (ESSD) storage type that delivers high performance. For more information, see [EOS/Discontinuation] End of sale for the standard SSD storage type for specific database engines in ApsaraDB RDS from July 01, 2022.

  • The maximum number of connections in this topic indicates the maximum number of processes that can be connected to the RDS instance at a time.

  • If you cannot select the required instance type when you change the specifications of an RDS instance, the instance type is not supported in this region. The supported instance types vary based on regions. The instance types displayed on the ApsaraDB RDS buy page shall prevail.

  • The public bandwidth of an RDS instance cannot be adjusted.

RDS instances on RDS High-availability Edition (with cloud disks)

Formulas to calculate the maximum I/O bandwidth of a cloud disk:

  • General ESSDs:

    • I/O burst disabled: min{350 + I/O bandwidth increment, Maximum I/O bandwidth supported by the instance type, 120 + 0.5 × Storage capacity + I/O bandwidth increment}

    • I/O burst enabled: min{4000, Maximum I/O bandwidth supported by the instance type}

  • ESSDs:

    • PL1 ESSD: min{120 + 0.5 × Storage capacity, 350, Maximum I/O bandwidth supported by the instance type}

    • PL2 ESSD: min{120 + 0.5 × Storage capacity, 750, Maximum I/O bandwidth supported by the instance type}

    • PL3 ESSD: min{120 + 0.5 × Storage capacity, 4000, Maximum I/O bandwidth supported by the instance type}

  • PL1 ESSD: 20 GB to 64,000 GB

  • PL2 ESSD: 500 GB to 64,000 GB

  • PL3 ESSD: 1,500 GB to 64,000 GB

  • Standard SSD: 20 GB to 6,000 GB

Note

ApsaraDB RDS for MySQL supports automatic storage expansion when the storage usage of an RDS instance reaches the threshold that you specify. For more information, see Configure automatic storage expansion.

An ApsaraDB RDS for MySQL cluster supports MySQL 5.7 and MySQL 8.0.

Important

RDS Cluster Edition for ApsaraDB RDS for MySQL is available for purchase in some regions. The following table describes the regions where RDS Cluster Edition for ApsaraDB RDS for MySQL is supported and the estimated release date in other regions. The actual release date prevails.

Formulas to calculate the maximum I/O bandwidth of a cloud disk:

  • General ESSDs:

    • I/O burst disabled: min{350 + I/O bandwidth increment, Maximum I/O bandwidth supported by the instance type, 120 + 0.5 × Storage capacity + I/O bandwidth increment}

    • I/O burst enabled: min{4000, Maximum I/O bandwidth supported by the instance type}

Note

If your RDS instance uses one of the following instance types and the pay-as-you-go billing method, the maximum storage capacity that is allowed for your RDS instance is increased from 2,000 GB to 3,000 GB in emergency situations.

  • mysql.x8.medium.2

  • mysql.x4.large.2

  • mysql.x8.large.2

If your RDS instance uses one of the preceding instance types and the used storage exceeds 2,000 GB, you cannot change the billing method from pay-as-you-go to subscription. You can change the billing method only when the used storage is less than 2,000 GB.

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 specifications.

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.
