c6a.32xlarge is AWS's compute-optimized EC2 size at 128 vCPU and 256 GiB. In the name, "c" stands for compute, "6" is the generation, "a" marks AMD processors and "32xlarge" is the size within the c6a family. It runs on AMD EPYC 7R13 Processor at 3.6 GHz, and AWS introduced it in February 2022. AWS has since shipped c7a, c8a and c9g; c7a.32xlarge is the direct replacement at this size, scoring 4,052,343 CoreMark/s against this instance's 2,731,929 — roughly 48% more throughput for the same vCPU count. The closest Spot shape is ch.vs1.2xlarge at 16 vCPU, so this instance maps to 8 of them — 128 vCPU and 256 GiB across the fleet, about 93% below the US East (N. Virginia) on-demand rate. Spot delivers compute as managed Kubernetes, so a node pool of that size is the native shape of the answer rather than a workaround — provided the workload scales horizontally.
