EC2 r8a instance prices
Memory optimized · AMD EPYC 9R45 Processor
The r8a series is a memory optimized EC2 line running on AMD EPYC 9R45. It has 10 sizes, from the r8a.medium with 1 vCPU and 8 GiB to the r8a.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 $0.0799/hour to $15.34/hour, or $58.31 to $11,196 a month. The median price per vCPU-hour across the series is $0.0799.
Every size costs the same $0.0799 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 7 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.
