Amazon Aurora now supports T3.large and medium instances as well as R5 class instances in AWS GovCloud (US) Regions. Using T3.large instances with Amazon Aurora is a cost-effective option for smaller workloads such as test, development, and QA, while still giving you the option to use larger class instances for production deployments. 

T3 instances provide a baseline level of CPU performance, with the ability to burst CPU usage at any time, for as long as required. They offer a balance of compute, memory and network resources, and are ideal for database workloads with moderate CPU usage that experience temporary spikes in use. 

When a workload is operating below the baseline threshold, your T3 instance accumulates CPU credits. Each earned CPU credit provides the instance with the opportunity to burst with the performance of a full CPU core for one minute when needed. Amazon Aurora T3 instances are configured for Unlimited Mode, which means they can burst beyond the baseline over a 24-hour window for an additional charge.

R5 instances are the latest generation of memory optimized instances that deliver 5% additional memory per vCPU than R4, with the largest size providing 768 GiB of memory, allowing customers to scale up and consolidate their workloads on a fewer number of instances. In addition, R5 instances deliver a 10% price per GiB improvement and a ~20% increase in CPU performance over R4.

You can easily create a new Aurora T3 and R5 instance, or modify your existing Aurora database instance to scale to T3, 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 is a MySQL and PostgreSQL-compatible relational database built for the cloud that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open source databases.
