Deploying and Debugging HTTP/3 - Challenges and Solutions

Explore the complexities of deploying and debugging modern networking protocols like QUIC and HTTP/3 in this technical deep-dive conference talk from SREcon23 Europe/Middle East/Africa. Delve into the challenges posed by fully encrypted protocols, even at the transport layer, and learn about key features such as packet header protection, 0-RTT, alt-svc, resource prioritization, and connection migration. Discover how these elements can impact the setup, load balancing, and firewalling of real-world QUIC deployments at scale. Gain insights into practical debugging options, including curl, wireshark, and specialized qlog and qvis tooling. Benefit from "tales from the trenches" shared by industry giants like Akamai, Google, Meta, and Cloudflare, including the intriguing story of how Google accidentally DDoSed itself, forcing a week-long QUIC shutdown. Enhance your understanding of modern networking protocols and their implementation challenges in this informative 43-minute presentation by Robin Marx from Akamai.
