The m8a.large pairs 2 vCPU with 8 GiB of RAM, the 4.00 GiB-per-vCPU ratio that marks a general-purpose instance. In the name, "m" is the general-purpose line, "8" is the generation, "a" marks AMD processors and "large" is the size within the m8a family. It runs on AMD EPYC 9R45 Processor at Up to 4.5 GHz, and AWS introduced it in October 2025. AWS has since shipped m9g; m9g.large is the direct replacement at this size. gp.vs2.large is the closest Spot shape: 4 vCPU and 16 GiB, so 2 more vCPU and 8 GiB more memory, about 91% below the US East (N. Virginia) on-demand rate.
