Resilient Systems

podcast: RunAs Radio Resiliency with Michael Nygard

circulareconomy - Resilience vs Efficiency:
“Resilience is the capacity of a system to absorb disturbance and reorganise while undergoing change so as to still retain essentially the same function, structure, identity, and feedbacks.”"

"A system is brittle if it is unable to effectively absorb shock"

Consider a plate glass window in comparison to a trampoline net. 

The plate glass window can take a significant shock without budging, but at some point it can no longer absorb an impact and fractures. It is brittle. 

The trampoline net, on the other hand, will be moved by even a minor impact, but because of its ability to deform and stretch, it will not fracture (or tear) until far greater stress is applied then is needed to break the glass window. 


Resilience (network) - Wikipedia, the free encyclopedia
In computer networking: “Resiliency is the ability to provide and maintain an acceptable level of service in the face of faults and challenges to normal operation.”
