I built a system that did something very like this at a previous employer. We got really quick (mostly) atomic deployments which could be rolled-back instantly with one command.

Even at the time I thought Docker would be a great solution to the problem, but the organization was vehemently against using modern tech to manage servers and deployments, so I ended up writing that tool in bash instead. Good times.
