c8a.24xlarge pricing and specs in EU (Ireland)
96 vCPU · 192 GiB · 40 Gigabit · AMD EPYC 9R45 Processor
$5.5502/hour on-demand · $4,052/month (Linux, Shared)
c8a.24xlarge is a compute-optimized EC2 instance with 96 vCPU and 192 GiB, generation 8 of the c family. On-demand it costs $5.5502 an hour, about $4,052 a month if it runs all month. A one-year commitment with nothing up front works out at $3.6743 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 $2.5305 an hour, 54% below on-demand. The newer c8g.24xlarge offers the same size for $4.0934 an hour, 26% less and moves to Graviton. Across regions the cheapest place to run c8a.24xlarge is US East (N. Virginia) (us-east-1) at $5.1730 an hour, 7% 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.
