Amazon Aurora and RDS for PostgreSQL, MySQL, and MariaDB now offer Reserved Instances for R8g and M8g instances

Customers running Amazon Aurora and RDS for PostgreSQL, MySQL, and MariaDBdatabases can now purchase Reserved Instances for Graviton4-based R8g and M8g instances. These instances provide larger sizes up to 48xlarge with an 8:1 ratio of memory to vCPU and the latest DDR5 memory. Graviton4-based instances deliver up to 40% performance improvement and 29% better price-performance compared to equivalent Graviton3-based instances.

Reserved Instances offer significant savings over On-Demand rates with three flexible payment options: All Upfront providing the highest discount, Partial Upfront balancing between upfront and hourly payments, and No Upfront requiring no initial payment. Reserved Instances for 8th generation Graviton instances (R8g and M8g) offer deeper discounts as compared to the 7th generation Graviton instances (R7g and M7g), further improving the price-performance for these instances and enhancing cost-optimization opportunities. Reserved Instances provide instance size flexibility within the same family and automatically apply to both Single-AZ and Multi-AZ configurations, making them ideal for varying production workloads.

These 1-year Reserved Instances are available for Aurora MySQL, Aurora PostgreSQL, RDS for MySQL, RDS for PostgreSQL, and RDS for MariaDB in all AWS regions where Graviton4-based instances are offered with On-Demand pricing. For information on specific engine versions that support these DB instance types, refer to Aurora and RDS documentation.
