SREs improve the reliability of production systems, and reducing mean-time-to-repair (MTTR) is their top priority. While increasing automation is a key goal, organizations will lose their derived efficiency if enablement is arduous and time-consuming. As a result, they must build a layer of automation on top of their tooling.
