The table says CPUs, not vCPUs. Unless they're using single threaded single core processors, I think snc1.medium would equal either at least 4 vCPUs. I don't think they use the term vCPU for Snowcone so in reality it has zero vCPUs. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance...
- snc1.micro, CPUs: 1, memory: 1 GiB
- snc1.small, CPUs: 1, memory: 2 GiB
- snc1.medium, CPUs: 2, memory: 4 GiB
