Amazon RDS and Aurora Expand Graviton4-Based R8g and M8g Instances to Additional AWS Regions
Amazon Web Services has expanded the regional availability of its latest AWS Graviton4-powered database instances, specifically the memory-optimized R8g and general-purpose M8g instance families. This update applies to Amazon Aurora with MySQL and PostgreSQL compatibility, as well as Amazon RDS for PostgreSQL, MySQL, and MariaDB. These database instances are designed to provide significant price-performance improvements over previous-generation Graviton processors.

| Aspect | Before / Alternative | After / This |
|---|---|---|
| Processor Architecture | AWS Graviton3 (R7g / M7g) | AWS Graviton4 (R8g / M8g) providing higher compute efficiency |
| Regional Availability | Limited to initial launch regions | Expanded to Asia Pacific (Hyderabad, Melbourne, Malaysia) and Europe (London, Paris, Zurich) |
| Supported Engines | Standard instance classes with older CPU generations | Amazon Aurora (MySQL/PostgreSQL) and Amazon RDS (PostgreSQL/MySQL/MariaDB) |
Action Checklist
- Verify engine compatibility in the target AWS region Ensure your PostgreSQL, MySQL, or MariaDB version is compatible with Graviton4 instances.
- Test performance in a staging environment Evaluate the workload performance on R8g or M8g instance types before upgrading production databases.
- Modify the instance type using AWS Console, CLI, or Infrastructure as Code Plan for temporary downtime during the instance type modification unless using Multi-AZ deployments with minimal disruption.
