I don't think there is such a thing. Best case scenario is a lot of automation and monitoring. Where I work our dev / engineering team is investigating machine learning to automate repair a bit better. For example, over a 7 day period we record data for load on our backend and that ML model predicts and generates autoscaling rules according to historical data. Some of our services are about as low maintenance as I would think they can get (autoscaling, autoremoving poorly performing instances, etc) but I'd like to improve and only make an engineer get involved when the system can't be trusted to make the right call.
