Sōzu: A Hot Reconfigurable Reverse HTTP Proxy in Rust
Explore the architecture and capabilities of Sōzu, a hot reconfigurable reverse HTTP proxy, in this 30-minute Rust conference talk. Discover how to create a Rust program that can run continuously without interruption, even during configuration changes or binary upgrades, while handling traffic for thousands of applications across multiple virtual machines. Learn about the proxy's streaming HTTP parser built with nom, its single-threaded worker managing events with mio, and the associated tooling for command and control. Delve into topics such as multiprocess architecture, recovery from failure, TLS termination, and the challenges of proxy complexity. Gain insights from speaker Geoffroy Couprie on building resilient and scalable proxy solutions using Rust.
