The c7gd.12xlarge pairs 48 vCPU with 96 GiB of RAM, the 2.00 GiB-per-vCPU ratio that marks a compute-optimized instance. In the name, "c" stands for compute, "7" is the generation, "gd" marks AWS Graviton (ARM) processors and local NVMe storage and "12xlarge" is the size within the c7gd family. It runs on AWS Graviton3 Processor at 2.5 GHz, and AWS introduced it in July 2023. AWS has since shipped c8gd and c9gd; c8gd.12xlarge is the direct replacement at this size. Spot's node ladder tops out below this size, so c7gd.12xlarge becomes 3 × ch.vs1.2xlarge (48 vCPU, 96 GiB combined), about 94% 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.
