EC2 i8g instance prices

The i8g series is a storage optimized EC2 line running on AWS Graviton4. It has 9 sizes, from the i8g.large with 2 vCPUs and 16 GiB to the i8g.48xlarge with 192 vCPUs and 1536 GiB, and it is memory-heavy with a median of 8.0 GiB per vCPU.

In US East the Linux on-demand price runs from $0.1716/hour to $16.47/hour, or $125 to $12,026 a month. The median price per vCPU-hour across the series is $0.0858. These are Arm (Graviton) instances, which need arm64 builds of your software.

Every size costs the same $0.0858 per vCPU-hour, so price scales linearly: doubling the size doubles the bill, and two smaller instances cost exactly as much as one larger one. That makes it easy to start small and resize later without changing your unit cost. Availability varies by size: 8 of 9 sizes reach 12 of the 12 regions we track, while i8g.48xlarge is sold in fewer.
