r5n.4xlarge pricing and specs in Asia Pacific (Mumbai)

16 vCPU · 128 GiB · Up to 25 Gigabit · Intel Xeon Platinum 8259 (Cascade Lake)

$1.2240/hour on-demand · $894/month (Linux, Shared)

r5n.4xlarge is a memory-optimized EC2 instance with 16 vCPU and 128 GiB, generation 5 of the r family. On-demand it costs $1.2240 an hour, about $894 a month if it runs all month. A one-year commitment with nothing up front works out at $0.7710 an hour and pays for itself above roughly 459 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.4315 an hour, 65% below on-demand. The newer r6g.4xlarge offers the same size for $0.5200 an hour, 58% less and moves to Graviton. Across regions the cheapest place to run r5n.4xlarge is US East (N. Virginia) (us-east-1) at $1.1920 an hour, 3% 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.
