i3.4xlarge pricing and specs in EU (Ireland)

16 vCPU · 122 GiB · Up to 10 Gigabit · Intel Xeon E5-2686 v4 (Broadwell)

$1.3760/hour on-demand · $1,004/month (Linux, Shared)

i3.4xlarge is a storage-optimized EC2 instance with 16 vCPU and 122 GiB, generation 3 of the i family. On-demand it costs $1.3760 an hour, about $1,004 a month if it runs all month. A one-year commitment with nothing up front works out at $0.9410 an hour and pays for itself above roughly 499 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.5820 an hour, 58% below on-demand. The newer i4g.4xlarge offers the same size for $1.3616 an hour, 1% less and moves to Graviton. Across regions the cheapest place to run i3.4xlarge is US East (N. Virginia) (us-east-1) at $1.2480 an hour, 9% below EU (Ireland).

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.
