Amazon Aurora with MySQL compatibility now supports T3.large instances, in addition to the T3.medium, T3.small, and R5 class instances already available. Using T3.large instances with Amazon Aurora MySQL is a cost-effective option for smaller workloads such as test, dev, 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. 

You can easily create a new Aurora MySQL T3 instance, or modify your existing Aurora database instance to scale to T3, in the Amazon RDS Management Console or download the latest AWS SDK or CLI. Read the Aurora Documentation to learn more, 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 throughput than standard MySQL together with increased scalability, durability, and security.
