Amazon Aurora now supports AWS Graviton2-based T4g database instances in the AWS GovCloud (US) Regions. T4g database instances deliver a performance improvement of up to 49% over comparable current generation x86-based database instances. You can launch these database instances when using Amazon Aurora MySQL-Compatible Edition and Amazon Aurora PostgreSQL-Compatible Edition.
T4g 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. Amazon Aurora T4g 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 launch new instances in the Amazon RDS Management Console or using the AWS CLI. Upgrading a database instance to Graviton2 requires a simple instance type modification, using the same steps as any other instance modification. The T4g database instances are supported on Aurora MySQL 2.09.3 and higher, 2.10.0 and higher, 3.01.0 and higher, and on Aurora PostgreSQL 14.3 and higher, 13.3 and higher, 12.4 and higher, and 11.9 and higher versions. For more details, refer to the documentation.
The T4g database instances are now available in the commercial and AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions.
