Excerpt

Designing Data-Intensive Applications — Distilled Guide

Source: Martin Kleppmann, Designing Data-Intensive Applications Central thesis: Data is the core challenge of modern applications — not compute.

Pillar	Definition	Key Metric
Reliability	System works correctly even when faults occur	Fault ≠ Failure; tolerate faults, prevent failures
Scalability	System handles load growth gracefully	Measure with percentiles: p50, p95, p99, p999
Maintainability	System is easy to operate, understand, evolve	Operability + Simplicity + Evolvability
