Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Determining DB instance class support in Amazon Web Services Regions

To determine the DB instance classes supported by each DB engine in a specific Amazon Web Services Region, you can take one of several approaches. You can use the Amazon Web Services Management Console, the Amazon RDS Pricing page, or the describe-orderable-db-instance-options Amazon CLI command.

Note

When you perform operations with the Amazon Web Services Management Console, it automatically shows the supported DB instance classes for a specific DB engine, DB engine version, and Amazon Web Services Region. Examples of the operations that you can perform include creating and modifying a DB instance.

Using the Amazon RDS pricing page to determine DB instance class support in Amazon Web Services Regions

You can use the Amazon Aurora Pricing page to determine the DB instance classes supported by each DB engine in a specific Amazon Web Services Region.

To use the pricing page to determine the DB instance classes supported by each engine in a Region

  1. Go to Amazon Aurora Pricing.

  2. Choose an Amazon Aurora engine in the Amazon Pricing Calculator section.

  3. In Choose a Region, choose an Amazon Web Services Region.

  4. In Cluster Configuration Option, choose a configuration option.

  5. Use the section for compatible instances to view the supported DB instance classes.

  6. (Optional) Choose other options in the calculator, and then choose Save and view summary or Save and add service.

Using the Amazon CLI to determine DB instance class support in Amazon Web Services Regions

You can use the Amazon CLI to determine which DB instance classes are supported for specific DB engines and DB engine versions in an Amazon Web Services Region.

To use the Amazon CLI examples following, enter valid values for the DB engine, DB engine version, DB instance class, and Amazon Web Services Region. The following table shows the valid DB engine values.

Engine name Engine value in CLI commands More information about versions

For information about Amazon Web Services Region names, see Amazon Regions.

The following examples demonstrate how to determine DB instance class support in an Amazon Web Services Region using the describe-orderable-db-instance-options Amazon CLI command.

Listing the DB instance classes that are supported by a specific DB engine version in an Amazon Web Services Region

To list the DB instance classes that are supported by a specific DB engine version in an Amazon Web Services Region, run the following command.

For Linux, macOS, or Unix:

aws rds describe-orderable-db-instance-options --engine engine --engine-version version \
    --query "OrderableDBInstanceOptions[].{DBInstanceClass:DBInstanceClass,SupportedEngineModes:SupportedEngineModes[0]}" \
    --output table \
    --region region

For Windows:

aws rds describe-orderable-db-instance-options --engine engine --engine-version version ^
    --query "OrderableDBInstanceOptions[].{DBInstanceClass:DBInstanceClass,SupportedEngineModes:SupportedEngineModes[0]}" ^
    --output table ^
    --region region

The output also shows the engine modes that are supported for each DB instance class.

For example, the following command lists the supported DB instance classes for version 13.6 of the Aurora PostgreSQL DB engine in US East (N. Virginia).

For Linux, macOS, or Unix:

aws rds describe-orderable-db-instance-options --engine aurora-postgresql --engine-version 15.3 \
    --query "OrderableDBInstanceOptions[].{DBInstanceClass:DBInstanceClass,SupportedEngineModes:SupportedEngineModes[0]}" \
    --output table \
    --region us-east-1

For Windows:

aws rds describe-orderable-db-instance-options --engine aurora-postgresql --engine-version 15.3 ^
    --query "OrderableDBInstanceOptions[].{DBInstanceClass:DBInstanceClass,SupportedEngineModes:SupportedEngineModes[0]}"  ^
    --output table ^
    --region us-east-1

Listing the DB engine versions that support a specific DB instance class in an Amazon Web Services Region

To list the DB engine versions that support a specific DB instance class in an Amazon Web Services Region, run the following command.

For Linux, macOS, or Unix:

aws rds describe-orderable-db-instance-options --engine engine --db-instance-class DB_instance_class \
    --query "OrderableDBInstanceOptions[].{EngineVersion:EngineVersion,SupportedEngineModes:SupportedEngineModes[0]}" \
    --output table \
    --region region

For Windows:

aws rds describe-orderable-db-instance-options --engine engine --db-instance-class DB_instance_class ^
    --query "OrderableDBInstanceOptions[].{EngineVersion:EngineVersion,SupportedEngineModes:SupportedEngineModes[0]}" ^
    --output table ^
    --region region

The output also shows the engine modes that are supported for each DB engine version.

For example, the following command lists the DB engine versions of the Aurora PostgreSQL DB engine that support the db.r5.large DB instance class in US East (N. Virginia).

For Linux, macOS, or Unix:

aws rds describe-orderable-db-instance-options --engine aurora-postgresql --db-instance-class db.r7g.large \
    --query "OrderableDBInstanceOptions[].{EngineVersion:EngineVersion,SupportedEngineModes:SupportedEngineModes[0]}" \
    --output table \
    --region us-east-1

For Windows:

aws rds describe-orderable-db-instance-options --engine aurora-postgresql --db-instance-class db.r7g.large ^
    --query "OrderableDBInstanceOptions[].{EngineVersion:EngineVersion,SupportedEngineModes:SupportedEngineModes[0]}" ^
    --output table ^
    --region us-east-1
