r3.8xlarge pricing and specs in Asia Pacific (Mumbai)

32 vCPU · 244 GiB · 10 Gigabit · Intel Xeon E5-2670 v2 (Ivy Bridge) previous generation

$3.0320/hour on-demand · $2,213/month (Linux, Shared)

r3.8xlarge is a memory-optimized EC2 instance with 32 vCPU and 244 GiB, generation 3 of the r family; AWS lists it as a previous generation. On-demand it costs $3.0320 an hour, about $2,213 a month if it runs all month. A one-year commitment with nothing up front works out at $2.3100 an hour and pays for itself above roughly 556 hours a month; below that, on-demand is cheaper. The three-year options go down to $1.2743 an hour, 58% below on-demand. The newer r6g.8xlarge offers the same size for $1.0400 an hour, 66% less and moves to Graviton. Across regions the cheapest place to run r3.8xlarge is US East (Ohio) (us-east-2) at $2.6560 an hour, 12% below Asia Pacific (Mumbai).

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.

Caveat: instance price is only part of the bill. Cross-region and internet data transfer, latency to your users, data-residency rules and service availability can outweigh a few percent on compute.
