Do you have a link to this unicorn cloud machine ? I'm very interested for something faster than a bare-metal 32-cores threadripper with 128Gb of ram and a 2TB SSD (NVME I guess) for less than $1 an hour.
I agree with the root comment though that you may want to look at building in a cloud provider using spot instances. You’d have to invest in automation to spin up and tear down machines and manage build artifacts, but it might be more cost effective and operationally simpler than investing in your own hardware.
