I like the concept. But where I work, our infrastructure is currently hosted on leased dedicated servers, where (last time I checked) OS reloads require manual intervention from the hosting provider and cost something. So I guess the burning down and rebuilding would have to be done on a layer above the base OS, e.g. Docker containers.
