Amazon RDS for SQL Server

Now supports M8a and R8a instances powered by 5th Generation AMD EPYC processors. These instances deliver up to 70% higher throughput than comparable x86 instances for commonly used instance sizes.

Each vCPU in M8a and R8a instances corresponds to a physical CPU core, designed to deliver consistent per-core performance. Key features include:

  • Network Bandwidth: Up to 75 Gbps
  • EBS Bandwidth: Up to 60 Gbps
  • Optimize CPU Feature: Reduces vCPU-based Microsoft SQL Server licensing charges

These instances are available in all commercial AWS Regions where these instances are offered in Amazon EC2. Customers can purchase these instances using On-Demand pricing or as part of their Database Savings Plan.
