Determining DB instance class support in AWS Regions

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

Note

When you perform operations with the AWS Management Console, it automatically shows the supported DB instance classes for a specific DB engine, DB engine version, and AWS 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 AWS Regions

You can use the Amazon Aurora Pricing page to determine the DB instance classes supported by each DB engine in a specific AWS 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 AWS Pricing Calculator section.

3. In Choose a Region, choose an AWS 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 AWS CLI to determine DB instance class support in AWS Regions

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

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

Engine name	Engine value in CLI commands	More information about versions
MySQL 5.7-compatible and 8.0-compatible Aurora	aurora-mysql	Database engine updates for Amazon Aurora MySQL version 2 and Database engine updates for Amazon Aurora MySQL version 3 in the Release Notes for Aurora MySQL
Aurora PostgreSQL	aurora-postgresql	Release Notes for Aurora PostgreSQL

For information about AWS Region names, see AWS Regions.

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

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

To list the DB instance classes that are supported by a specific DB engine version in an AWS 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 AWS Region

To list the DB engine versions that support a specific DB instance class in an AWS 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
