Amazon Aurora Now Supports Additional Instance Sizes
The MySQL-compatible edition of Amazon Aurora has added support for db.r5.8xl, db.r5.16xl, and db.r5.24xl instance sizes.
R5 instances are based on the Amazon EC2 Nitro System, a combination of dedicated hardware and a lightweight hypervisor that delivers practically all 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 such as transaction processing, data warehousing, and analytics.
These instances are generally available on Aurora MySQL version 1.22.0 (compatible with MySQL 5.6) and Aurora MySQL version 2.06 (compatible with MySQL 5.7) and above. You can create a new R5 instance, or modify your existing Aurora database instance to scale up to the new instance sizes, in the Amazon RDS Management Console or download the latest AWS SDK or CLI. For pricing and regional availability, see Amazon Aurora Pricing.
Amazon Aurora combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. It provides up to five times better performance than the typical MySQL database and three times the performance of the typical PostgreSQL database, together with increased scalability, durability, and security.
