Amazon RDS for SQL Server now supports M8i and R8i instances
Amazon Relational Database Service (Amazon RDS) for SQL Server now supports M8i and R8i instances. These instances are powered by custom Intel Xeon 6 processors, available only on AWS, delivering the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud. The M8i and R8i instances offer up to 15% better price-performance and 2.5x more memory bandwidth compared to equivalent 7th generation Intel-based instances.
To use the new M8i and R8i instances, you can modify your existing RDS database instance or create a new RDS database instance from the RDS Management Console, or using the AWS SDK or CLI.
