Amazon Aurora now supports Graviton4-based R8g database instances

AWS Graviton4-based R8g database instances are now generally available for Amazon Aurora with PostgreSQL compatibility and Amazon Aurora with MySQL compatibility in US East (N. Virginia, Ohio), US West (Oregon), and Europe (Frankfurt) regions. R8g instances offer larger instance sizes, up to 48xlarge and features an 8:1 ratio of memory to vCPU, and 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 databases, depending on database engine, version, and workload. You can spin up R8g database instances in the [Amazon RDS Management Console](https://console.aws.amazon.com/rds/home) or using the [AWS CLI](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.CreateInstance.html). Upgrading a database instance to R8g instance family requires a simple instance type modification. For more details, refer to the [Aurora documentation](https://docs.amazonaws.cn/en%5Fus/AmazonRDS/latest/AuroraUserGuide/Aurora.Modifying.html). Amazon Aurora is designed for unparalleled high performance and availability at global scale with PostgreSQL compatibility. It provides built-in security, continuous backups, serverless compute, up to 15 read replicas, automated multi-Region replication, and integrations with other AWS services.
