c8i.xlarge pricing and specs in EU (Ireland)
4 vCPU · 8 GiB · Up to 12.5 Gigabit · Intel Xeon Scalable (Granite Rapids)
$0.2011/hour on-demand · $147/month (Linux, Shared)
c8i.xlarge is a compute-optimized EC2 instance with 4 vCPU and 8 GiB, generation 8 of the c family. On-demand it costs $0.2011 an hour, about $147 a month if it runs all month. A one-year commitment with nothing up front works out at $0.1331 an hour and pays for itself above roughly 483 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.0917 an hour, 54% below on-demand. The newer c8g.xlarge offers the same size for $0.1706 an hour, 15% less and moves to Graviton. Across regions the cheapest place to run c8i.xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $0.1837 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.

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.
