resiliency is not efficient

Jan 31, 2024

What's common to all these approaches - robustness, redundancy, and resilience, especially through diversity and decentralization - is that they are not efficient. Making systems resilient is fundamentally at odds with optimization, because optimizing a system means taking out any slack. A truly optimized, and thus efficient, system is only possible with near-perfect knowledge about the system, together with the ability to observe and implement a response. For a system to be reliable, on the other hand, there have to be some unused resources to draw on when the unexpected happens
