CloudFlare And Open Source Software: A Two-Way Street

This post details Cloudflare's philosophy and practice of engaging with open source software. It highlights the company's reliance on open source projects like nginx, PostgreSQL, and Kyoto Tycoon, and its contributions back to the community through releasing its own open source tools (e.g., golog, lua-cmsgpack, CNAME flattener) and hiring developers to work on critical open source projects (e.g., ngx_lua module, TLS Session Ticket keys for nginx). It also mentions sponsoring LuaJIT for performance improvements. The post emphasizes the benefits of open sourcing modifications, such as the 'many eyeballs' effect and reducing fork costs, and expresses a long-term goal of open-sourcing all major components.
