Amazon Relational Database Service (Amazon RDS) for SQL Server launches memory-optimized X2m database instances. Based on the Amazon EC2 X2iedn instance, X2m database instances provide the Amazon RDS Optimize CPU feature, which allows customers to reduce SQL Server software licensing costs by 50% or more compared to Amazon RDS x2iedn database instances for memory-intensive database workloads. X2m instances offer up to 64 vCPUs, up to 4 TB memory, up to 256K IOPS, and up to 32:1 memory to vCPU ratio.
To use the X2m 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. X2m instances can be purchased using On-Demand pricing, and qualify for AWS Database Savings Plan. See Amazon RDS for SQL Server Pricing for up-to-date pricing of instances, storage, data transfer and regional availability.
