Amazon RDS for PostgreSQL, MySQL, and MariaDB now supports M9g database instances

Source: AWS What's New

Share

AWS Graviton5-based M9g database (DB) instances are now generally available for Amazon Relational Database Service (RDS) for PostgreSQL, MySQL, and MariaDB. Graviton5-based instances provide up to a 30% performance improvement and up to a 23% price/performance improvement for on-demand pricing over Graviton4-based instances of equivalent sizes on Amazon RDS open source databases, depending on database engine, version, and workload. AWS Graviton5 processors are the latest generation of custom-designed AWS Graviton processors built on the AWS Nitro System. M9g DB instances are available with new

Why this matters
Why now

AWS continues to iterate rapidly on its custom silicon strategy, driven by both internal optimization and competitive pressures in the cloud computing market.

Why it’s important

This incremental improvement in price/performance for database instances reinforces AWS's competitive advantage and encourages migration to their optimized infrastructure, potentially impacting competitors and software vendors.

What changes

Cloud users, particularly those with database-heavy workloads on AWS, now have access to more performant and cost-efficient instances, allowing for potential workload consolidation or improved application responsiveness.

Winners
  • · AWS
  • · Companies using AWS RDS
  • · PostgreSQL, MySQL, and MariaDB ecosystems
Losers
  • · AWS cloud competitors
  • · Companies not optimizing cloud spend
Second-order effects
Direct

AWS customers will experience reduced operational costs or increased performance from their relational databases.

Second

This deepens customer lock-in for AWS as they further differentiate their custom hardware offerings from generic cloud instances.

Third

Increased adoption of Graviton-based instances might influence broader software development to prioritize ARM-compatible architectures, impacting multi-cloud strategies.
