An open-source book (CC BY-NC-ND) titled 'Philosophical Principles of High Concurrency' (PPHC) by Lv Wenhan, with 12 chapters and 83 articles covering high-concurrency system design. It walks from static/dynamic separation through Nginx, epoll, Kubernetes, load balancers, SDN, distributed databases, caching, and microservices up to a planet-scale architecture, and is also published in print by Publishing House of Electronics Industry.

Use cases

• learn high concurrency system design from first principles
• understand how Nginx and epoll achieve high performance
• study load balancing, LVS, and SDN-based clusters
• learn distributed database evolution from middleware to NewSQL
• prepare for backend architecture interview questions
• understand caching and message queue architecture for flash sales
• design scalable microservice and infinitely scalable architectures

When to choose

• you want a deep, narrative-driven explanation of high-concurrency and distributed systems concepts
• you are preparing for backend or architecture interviews
• you want free, well-regarded reading material spanning infrastructure, networking, databases, and scaling
• you prefer Chinese-language technical books with practical case studies

When to avoid

• you need hands-on code tutorials or runnable reference implementations
• you need a formally licensed resource for commercial redistribution (CC BY-NC-ND forbids commercial use and derivatives)
• you want an English-language textbook
• you need up-to-date vendor-specific documentation rather than conceptual principles
