You can now launch R3 and T2 instances when using Amazon RDS for MySQL, MariaDB, PostgreSQL, Oracle and SQL Server in the AWS GovCloud (US) region. R3 instances are optimized for memory-intensive applications and have the lowest cost per GiB of RAM among the Amazon EC2 instance types. T2 instances provide a baseline level of CPU performance with the ability to burst above the baseline. The bursting model is based on “CPU Credits” that accumulate during quiet periods for spending when things get busy. To learn more about the benefits of the R3 and T2 instance families on Amazon RDS, visit the documentation page. For more information on pricing, visit the pricing page.

The R3 and T2 instances families are available with MySQL database version 5.6; MariaDB database version 10.0; PostgreSQL database versions 9.3 and 9.4; Oracle database versions and; and SQL Server Standard and Enterprise Editions database versions 2008, 2012, and 2014. You can create new R3 and T2 instances with just a few clicks using the "Launch DB Instance" wizard in the AWS Management Console. To migrate an existing instance, first upgrade your instance to one of the database versions listed above, and then restore a snapshot of that database instance to a new R3 or T2 instance. 

Amazon RDS is also making available the new and simplified Reserved Instance purchase options announced on June 15th, 2015 in the AWS GovCloud (US) Region. As part of this simplification, you will no longer be able to purchase the Light or Medium Utilization Reserved Instances on or after May 11th, 2016. For complete information on these new cost-saving options, visit the RDS Reserved Instance page.
