Hi, it's Shii-chan!

AWS What's New aws.amazon.com

There's a new database instance type. Let's look at the specs!

What was announced?

According to AWS What's New, Amazon Aurora and Amazon RDS now support R8a database instances powered by 5th generation AMD EPYC processors. That expands the choices available for your database workloads!

What changes

In R8a database instances, each vCPU corresponds to a physical CPU core, which delivers consistent per-core performance.

For workloads with high I/O requirements, the bandwidth is:

  • Up to 75 Gbps of network bandwidth
  • Up to 60 Gbps of Amazon EBS bandwidth

All R8a instances are built on the AWS Nitro System using sixth-generation Nitro Cards.

Dive Deep

Supported engines:

  • Amazon Aurora PostgreSQL-Compatible Edition
  • Amazon Aurora MySQL-Compatible Edition
  • RDS for PostgreSQL
  • RDS for MySQL
  • RDS for MariaDB

Available Regions:

  • US East (N. Virginia, Ohio)
  • US West (Oregon)
  • Canada (Central)
  • Asia Pacific (Tokyo, Taipei)
  • Europe (Ireland, Frankfurt, Spain)

You can get started through the Amazon RDS Management Console or the AWS CLI. For the engine versions that support these instance classes, see the Aurora and RDS documentation, and see the pricing pages for costs.

Wrap-up

  • Aurora and RDS support R8a with 5th generation AMD EPYC
  • One vCPU per physical core, with up to 75 Gbps networking and 60 Gbps EBS
  • Available for two Aurora engines and three RDS engines, in nine Regions

This is for ops folks who want to revisit database I/O performance and instance choices!
