I work on a service with high OLA requirements. I'm terrified everytime I roll out a new build or config change, in spite of having tested them thoroughly. At the scale at which these things operate, it's very difficult to manually imagine all the possible ways things can go wrong. Especially when you have multiple services that are all interdependent on each other and written/maintained by different teams in different geographic locations. I'm sure there is lots of research happening in this area within Microsoft and Google. Can't wait to have this sooner.
