EC2 c8a instance prices
Compute optimized · AMD EPYC 9R45 Processor
The c8a series is a compute optimized EC2 line running on AMD EPYC 9R45. It has 10 sizes, from the c8a.medium with 1 vCPU and 2 GiB to the c8a.48xlarge with 192 vCPUs and 384 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 $0.0539/hour to $10.35/hour, or $39.34 to $7,553 a month. The median price per vCPU-hour across the series is $0.0539.
Every size costs the same $0.0539 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 6 of the 12 regions we track. Each size below links to a page with prices in every tracked region, reserved-instance savings, Windows pricing and cheaper alternatives of the same shape.
