Antifragility@dlutzy

Fragile Robust

Fragile Robust

Antifragile

Fragile Example: glass

Shatters when exposed to even a small stressor.

Robust Example: steel bar

Resists even a large amount stress. But is inflexible. When exposed to enough stress it breaks.

Antifragile Example: muscle

When exposed to stress it gets stronger.

Is this idea applicable to computer systems?

“if antifragility is the property of all those natural (and complex) systems that have survived, depriving these systems of volatility, randomness, and stressors will harm them.” - Taleb

Without change something sleeps inside us, and seldom awakens. The sleeper must awaken.

- Duke Leto Atreides

Antifragility is all around us, if we look for it.

Continouous integration/deployment == antifragile

Legacy systems == robust or (more likely) fragile
