Is this not the perfect (and intended) use case for VM's, Containers, "Serverless" Functions and other mechanisms that all ride on top of already booted physical hardware? It seems to me this particular use case is a lot like wanting a forklift capable of driving highway speeds. Can it be done? Sure. But then you sacrifice a lot of what made a forklift good at it's intended job. There is nothing to be gained from running short-lived code directly on physical servers. Today's Hypervisors are very good at not getting in the way - ie. there is little to zero performance penalty from running a VM, particularly a VM with dedicated resources. In any event - what you desire can already be achieved, just not with your typical IBM/Dell/HP/Whatever server platforms. The things that make these computers desirable (and earn the denotation of a "server") for long-running systems are unnecessary if the goal is to boot, execute some code, shutdown, repeat. Off the shelf commodity "desktop" hardware is fully capable of booting in seconds and executing code - you just lose all the redundancy/reliability - but that's not needed under this scenario anyway.
