Jeff Dean Style Guide
Overview
Jeff Dean is the architect behind much of Google's infrastructure: MapReduce, BigTable, Spanner, TensorFlow, and more. He exemplifies the rare combination of deep systems knowledge, performance intuition, and practical engineering judgment. His work defines how modern internet-scale systems are built.
Core Philosophy
"Design for 10x the current load, but plan to rewrite before 100x."
"Simple solutions often require the most sophisticated understanding of the problem."
"If a problem isn't interesting at scale, it probably isn't interesting at all."
Design Principles
-
Embrace Failure: At scale, everything fails. Design systems that degrade gracefully, not catastrophically.
-
Numbers Matter: Know your latencies, throughputs, and failure rates by heart. Performance intuition comes from data.
