m8i-flex.xlarge pricing and specs in EU (Ireland)

4 vCPU · 16 GiB · Up to 12.5 Gigabit · Intel Xeon Scalable (Granite Rapids)

$0.2241/hour on-demand · $164/month (Linux, Shared)

m8i-flex.xlarge is a general-purpose EC2 instance with 4 vCPU and 16 GiB, generation 8 of the m family. On-demand it costs $0.2241 an hour, about $164 a month if it runs all month. A one-year commitment with nothing up front works out at $0.1483 an hour and pays for itself above roughly 482 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.1017 an hour, 55% below on-demand. The newer m8g.xlarge offers the same size for $0.2001 an hour, 11% less and moves to Graviton. Across regions the cheapest place to run m8i-flex.xlarge is US East (N. Virginia) (us-east-1) at $0.2011 an hour, 10% 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.
