Architecture of Internet Product is an open-source collection of technical architecture materials from major internet companies and large-scale online systems. The repository organizes presentations, articles, diagrams, and reference documents that describe how real production platforms have approached high concurrency, e-commerce, backend infrastructure, and large distributed services.

The collection includes company-oriented material covering organizations such as Tencent, Alibaba, Meituan, Baidu, and others, alongside topic-based architecture resources and links to open-source projects produced by major Chinese technology companies. Contributors can add notable architecture presentations, PDFs, and articles through pull requests or issues.

The repository is primarily a learning and reference archive rather than an executable software project. It is useful for backend engineers, architects, and technical leaders who want examples of production architecture decisions and historical approaches used by large internet businesses.
