You can now launch T3 instance types when using Amazon Relational Database Service (RDS) for MySQL and Amazon RDS for MariaDB. Amazon EC2 T3 instances are the next generation burstable general-purpose instance type that provide a baseline level of CPU performance with the ability to burst CPU usage for any period of time, whenever and however long required.

T3 instances 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. T3 instances accumulate CPU credits when a workload is operating below the baseline. Each earned CPU credit provides the T3 instance the opportunity to burst with the performance of a full CPU core for a minute. Amazon RDS 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 scale up to the new instance types by modifying your existing DB instance in the AWS RDS Management Console. Refer to the Amazon RDS User Guide for more details.
