The MySQL-compatible edition of Amazon Aurora has added support for R5 instances, the next generation of Amazon EC2 memory-optimized instances.

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. Depending on your workload, you may be able to achieve up to a 70% performance boost as compared to R4 instances.

You can easily create a new R5 instance, or modify your existing Aurora database instance to scale up to R5, in the Amazon RDS Management Console. Please refer to the Amazon Aurora User Guide for more details, and to find out which Aurora versions are supported. 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, together with increased scalability, durability, and security.
