I'm interested in how they 'hibernate'/save the state of the instances within the shutdown time limit. I was also looking into this for myself, there are ways of using docker to save the in-process memory a-la hibernate, which would work well with this. But, especially for GCP where you only get ~60 seconds between the shutdown signal and hard stop, I was worried that it wouldn't save it fast enough. I often work on pretty high-ram instances and thought even saving from ram to disk would take too long for 150-300GB ram uses.

I hadn't heard of nimbo, maybe I can read how they're doing it since it's open sources. Does anyone have any idea how they're saving state so fast (NVME SSD disk?)
