About this episode

This episode features a discussion with Cloudflare's Edward Wang and Kevin Guthrie about their Rust-based proxy, Pingora, and the challenges of scaling infrastructure.

How do you build a system that handles 90 million requests per second? That's the scale that Cloudflare operates at, processing roughly 25% of all internet traffic through their global network of 330+ edge locations. In this episode, we talk to Kevin Guthrie and Edward Wang from Cloudflare about Pingora, their open-source Rust-based proxy that replaced nginx across their entire infrastructure. We'll find out why they chose Rust for mission-critical systems handling such massive scale, the technical challenges of replacing battle-tested infrastructure, and the lessons learned from "oxidizing" one of the internet's largest networks.
