You can now launch R5 instance types when using HAQM Relational Database Service (RDS) for MySQL and HAQM RDS for MariaDB. HAQM EC2 R5 instances are the next generation of HAQM EC2 memory optimized instances. R5 instances are based on the HAQM EC2 Nitro System, a combination of dedicated hardware and lightweight hypervisor which delivers practically all of the compute and memory resources of the host hardware to your database instance.

With a 1:8 vCPU to memory ratio, R5 instances are well suited for running memory intensive database workloads including transaction processing, data warehousing, and analytics. R5 instances introduce a new larger instance size, r5.24xlarge, which provides 96 vCPUs and 768GiB of memory per instance. Depending on your workload, you may be able to achieve up to a 39% performance boost with R5 instances compared to R4 instances.

You can scale up to the new instance types by modifying your existing DB instance in the AWS RDS Management Console. Refer to the HAQM RDS User Guide for more details.
