8 vCPU · 16 GiB · Up to 50 Gigabit · AWS Graviton4 Processor Graviton

$0.5354/hour on-demand · $391/month (Linux, Shared)

c8gn.2xlarge is a compute-optimized EC2 instance with 8 vCPU and 16 GiB, generation 8 of the c family on AWS Graviton (Arm). On-demand it costs $0.5354 an hour, about $391 a month if it runs all month. A one-year commitment with nothing up front works out at $0.3373 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 $0.2244 an hour, 58% below on-demand. The newer c8g.2xlarge offers the same size for $0.3411 an hour, 36% less. Across regions the cheapest place to run c8gn.2xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $0.4626 an hour, 14% 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.

List prices are where it starts. Your bill is where it matters.

TruCost reads your actual AWS usage and tells you which of these commitments you should really buy, what your idle capacity costs, and where every dollar of the bill goes. Thirty minutes on your own data.
