The difficult part is how to name the feature intuitively, adding to an ocean of jargon and documentation, and making the configuration knobs intuitive both in UI and CLI/SDK.
Other founder of Depot here. AWS is pretty close to this idea with their Warm Pools [0]. But for our use case, they're just too slow to react to changes. We observed 60s+ to notice a change and actually start the machine. That doesn't work when we need to launch the machine as quickly as possible in reaction to a pending GHA job.
That said, I think this is a problem they could likely solve with that functionality, and we'd love to use it.
The article talks about fio to warm the drive... That's basically fast snapshot restore[0]. This reduces the "first access" penalty for "dirty" blocks. This is probably the slowest part of the entire article (it's about 10 seconds per dirty GB to fio the disk).
Often the technology is the easier part.
