The author makes a convincing argument against doing this workload on on-demand instances, but what about spot instances? AWS explicitly calls out scientific computing as a major use case for scientific computing in its training/promotional materials. Given the advertised ~70-90% markdown on spot instance time, it seems like a great option compared to paying almost the same amount as the workstation but not having to pay to buy, maintain, or replace the hardware.
