r3.xlarge pricing and specs in US East (N. Virginia)
4 vCPU · 30.5 GiB · Moderate · Intel Xeon E5-2670 v2 (Ivy Bridge) previous generation
$0.3330/hour on-demand · $243/month (Linux, Shared)
r3.xlarge is a memory-optimized EC2 instance with 4 vCPU and 30.5 GiB, generation 3 of the r family; AWS lists it as a previous generation. On-demand it costs $0.3330 an hour, about $243 a month if it runs all month. A one-year commitment with nothing up front works out at $0.2090 an hour and pays for itself above roughly 458 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.1166 an hour, 65% below on-demand. The newer r6g.xlarge offers the same size for $0.2016 an hour, 39% less and moves to Graviton. Across regions the cheapest place to run r3.xlarge is US East (Ohio) (us-east-2) at $0.3320 an hour, 0% below US East (N. Virginia).

Newer generations of the same size
Same family letter and size in a newer generation, ranked by price. “vCPU per $” uses vCPU as the performance proxy — newer chips usually add more, so it is a floor.
