EC2 c5a instance prices

The c5a series is a compute optimized EC2 line running on AMD EPYC 7R32. It has 8 sizes, from the c5a.large with 2 vCPUs and 4 GiB to the c5a.24xlarge with 96 vCPUs and 192 GiB, and it is compute-heavy with a median of 2.0 GiB per vCPU.

In US East the Linux on-demand price runs from $0.0770/hour to $3.70/hour, or $56.21 to $2,698 a month. The median price per vCPU-hour across the series is $0.0385.

Every size costs the same $0.0385 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. All sizes are sold in the same 12 of the 12 regions we track.
