c5.9xlarge pricing and specs in EU (Ireland)

36 vCPU · 72 GiB · 12 Gigabit · Intel Xeon Platinum 8124M previous generation

$1.7280/hour on-demand · $1,261/month (Linux, Shared)

c5.9xlarge is a compute-optimized EC2 instance with 36 vCPU and 72 GiB, generation 5 of the c family; AWS lists it as a previous generation. On-demand it costs $1.7280 an hour, about $1,261 a month if it runs all month. A one-year commitment with nothing up front works out at $1.0890 an hour and pays for itself above roughly 460 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.6497 an hour, 62% below on-demand. The newer c5d.9xlarge offers the same size for $1.9620 an hour, 14% more. Across regions the cheapest place to run c5.9xlarge is Asia Pacific (Mumbai) (ap-south-1) at $1.5300 an hour, 11% 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.
