With the lowest cost per GiB of RAM out of all EC2 instance types, the R3 instance is best suited for memory intensive applications. Featuring high-frequency Intel Xeon (Ivy Bridge) processors and the ability to withstand a memory bandwidth of 63,000 MB per second, the R3 instance type tops its predecessors -- M2 and CR1 instances. Improvements to memory bandwidth, I/O performance, memory per instance and price point per GiB of RAM enable the R3 instance to offer higher performance.

The R3 instance works well for a high-performance cloud-based database, distributed memory cache or a larger SAP deployment.
