Amazon RDS for SQL Server

Amazon RDS for SQL Server now supports M8id and R8id instances, powered by custom Intel Xeon 6 processors with local NVMe SSD storage. These instances offer up to 384 vCPUs, 3 TiB of memory, and 22.8 TB of local NVMe SSD storage, providing 4x the vCPUs and memory and over 6x the local storage compared to M5d and R5d instances.

When using M8id or R8id instances, RDS for SQL Server automatically places the tempdb data and log files on the local NVMe instance store, reducing read and write latency for tempdb. Database data and log files remain on Amazon EBS, and snapshots are smaller and use less backup storage.

What to do

  • Modify existing RDS database instances or create new ones using the RDS Management Console, AWS SDK, or CLI.
  • Use M8id and R8id instances in the following regions: US East (N. Virginia), US East (Ohio), US West (Oregon), Canada (Central), Europe (Ireland), Europe (London), Europe (Frankfurt), Europe (Stockholm), Europe (Spain), Asia Pacific (Tokyo), Asia Pacific (Mumbai), Asia Pacific (Sydney), and Asia Pacific (Malaysia).
  • Check Amazon RDS for SQL Server Pricing for details.
