$1.3616/hour on-demand · $994/month (Linux, Shared)

i4g.4xlarge is a storage-optimized EC2 instance with 16 vCPU and 128 GiB, generation 4 of the i family on AWS Graviton (Arm).

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.
