DB instance class support for Microsoft SQL Server - Amazon Relational Database Service
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).

DB instance class support for Microsoft SQL Server

The computation and memory capacity of a DB instance is determined by its DB instance class. The DB instance class you need depends on your processing power and memory requirements. For more information, see DB instance classes.

The following list of DB instance classes supported for Microsoft SQL Server is provided here for your convenience. For the most current list, see the RDS console: https://console.amazonaws.cn/rds/.

Not all DB instance classes are available on all supported SQL Server minor versions. For example, some newer DB instance classes such as db.r6i aren't available on older minor versions. You can use the describe-orderable-db-instance-options Amazon CLI command to find out which DB instance classes are available for your SQL Server edition and version.

Note

  • Starting with the 7th generation instance class, hyper-threading is disabled on RDS SQL Server for instance sizes 2xlarge and above. This results in the total number of vCPUs available being half of that supported by the corresponding EC2 instance. For example, the EC2 instance type m7i.2xlarge by default supports 4 cores and 2 threadsPerCore, resulting in a total of 8 vCPUs. In contrast, the RDS for SQL Server db.m7i.2xlarge instance, with hyper-threading disabled, results in 4 cores and 1 threadsPerCore, overall 4 vCPUs.

  • Starting with the 7th generation instances, your billing provides a detailed breakdown of RDS DB instance and third-party licensing fees. For more details, refer to RDS SQL Server pricing.
