Large-Scale Architecture: The Unreasonable Effectiveness of Simplicity
summary
Argues that simplifying architecture—modular services, event-sourced immutable logs, async pipelines and materialized views—drives scale and reliability with concrete results: Amazon Aurora uses async redo-log distribution, Netflix processes ~1M viewing events/sec into materialized views, Stitch Fix models orders as event logs, eBay’s platform work doubles engineering productivity and raises deployment frequency, and Walmart collapses a 23-node synchronous hot path to an async design with only 23 synchronous calls to 2 in the customer-facing path, yielding far lower cost and meeting tight SLOs.
