c7gd.medium is AWS's compute-optimized EC2 size at 1 vCPU and 2 GiB. In the name, "c" stands for compute, "7" is the generation, "gd" marks AWS Graviton (ARM) processors and local NVMe storage and "medium" 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.medium is the direct replacement at this size. Rackspace Spot maps this to ch.vs2.medium (2 vCPU, 4 GiB), giving you 1 more vCPU and 2 GiB more memory, $0.045/hr on AWS in US East (N. Virginia), from $0.002/hr on Rackspace Spot.
