Amazon Aurora PostgreSQL now supports R8g database instances in additional AWS regions

AWS Graviton4-based R8g database instances now available in new regions

AWS Graviton4-based R8g database instances are now generally available for Amazon Aurora with PostgreSQL compatibility in the AWS Canada (Central), AWS Asia Pacific (Singapore), and AWS Asia Pacific (Seoul) regions. These instances offer larger sizes, up to 48xlarge, and feature an 8:1 ratio of memory to vCPU, along with the latest DDR5 memory. Graviton4-based instances provide up to a 40% performance improvement and up to 29% price/performance improvement for on-demand pricing over Graviton3-based instances of equivalent sizes on Amazon Aurora PostgreSQL databases, depending on database engine, version, and workload.

R8g DB instances are available with new 24xlarge and 48xlarge sizes, offering up to 192 vCPU, up to 50Gbps enhanced networking bandwidth, and up to 40Gbps of bandwidth to the Amazon Elastic Block Store (Amazon EBS).

What to do

• Launch Graviton4 R8g database instances in the Amazon RDS Management Console or using the AWS CLI.
• Upgrade a database instance to Graviton4 by modifying the instance type.
• Refer to the Aurora documentation for more details.
