c6a.xlarge pricing and specs in EU (Ireland)

4 vCPU · 8 GiB · Up to 12.5 Gigabit · AMD EPYC 7R13 Processor

$0.1642/hour on-demand · $120/month (Linux, Shared)

c6a.xlarge is a compute-optimized EC2 instance with 4 vCPU and 8 GiB, generation 6 of the c family. On-demand it costs $0.1642 an hour, about $120 a month if it runs all month. A one-year commitment with nothing up front works out at $0.1087 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 $0.0651 an hour, 60% below on-demand. The newer c6g.xlarge offers the same size for $0.1459 an hour, 11% less and moves to Graviton. Across regions the cheapest place to run c6a.xlarge is Asia Pacific (Mumbai) (ap-south-1) at $0.0935 an hour, 43% 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.
