Amazon RDS and Aurora expand R8gd and M8gd to additional Regions

Amazon Relational Database Service (RDS) now supports R8gd database instances in 12 additional regions and and M8gd database instances in 6 additional Regions with Optimized Reads for Amazon Aurora PostgreSQL, RDS for PostgreSQL, RDS for MySQL, and RDS for MariaDB. R8gd and M8gd instances deliver up to 165% better throughput and up to 120% better price-performance over R6g instances for Aurora PostgreSQL. Optimized Reads uses local NVMe-based SSD block storage to store ephemeral data such as temporary tables, reducing network storage access and improving query latency.
