These instances provide high network and EBS bandwidth, suitable for I/O-intensive applications.

R8a instances utilize the AWS Nitro System with sixth-generation Nitro Cards and are compatible with Aurora PostgreSQL, Aurora MySQL, and RDS for PostgreSQL, MySQL, and MariaDB. Availability spans multiple AWS regions worldwide, accessible via the AWS Management Console and CLI, with specific engine version requirements detailed in AWS documentation.
