This document summarizes the technical evolution of Taobao over the past 10 years. It describes the architecture and technologies used in each major version from 2003 to the present. Key aspects included moving from a LAMP stack to Java EE, adopting distributed databases, caching, and service frameworks. Transaction volumes grew enormously from 50 million RMB in 2011 to over 350 billion RMB in 2013. The document advocates for incremental improvement over time and references Big Data as an ongoing challenge.
