The blast radius: the operating risk your cost model can't see
Every operation gets mapped by cost and by the org chart. Neither of those maps tells you the one thing that decides your worst day: how far a single failure spreads. And the efficiency moves everyone rewards — consolidating onto one provider, one system, one source of truth, and stripping out the slack — quietly maximise that spread. This is a way to see the blast radius your cost model hides, to price the trade-off honestly, and to shrink it at the few nodes that matter without giving up the efficiency everywhere else.
