This is something System Administrators aquire as knowledge along the way (as the homeostasis provider that they are). This is something that developers always ignore for they do not operate the systems that they build either on scale or for long enough to understand how what they built works. This is something that every DevOp and their managers should be prepared for:
“Complex systems possess potential for catastrophic failure. Human practitioners are nearly always in close physical and temporal proximity to these potential failures – disaster can occur at any time and in nearly any place. The potential for catastrophic outcome is a hallmark of complex systems. It is impossible to eliminate the potential for such catastrophic failure; the potential for such failure is always present by the system’s own nature.” — How Complex Systems Fail
If people expect that the software intensive systems that they use are like bridges, they should be prepared for Tacoma Narrows.
