Deliver Great Experiences with Quic on Amazon Cloudfront Net401

Title

AWS re:Invent 2022 - Deliver great experiences with QUIC on Amazon CloudFront (NET401)

Summary

  • Jim Roskind, with Mahmoud Raghab, discussed the benefits of using QUIC (Quick UDP Internet Connections) on Amazon CloudFront.
  • QUIC is a protocol designed to replace HTTP and provides cryptographic privacy, tamper resistance, and multiplexing requests to improve latency and reduce variance.
  • QUIC evolved into the IETF's HTTP/3 standard and is supported by Amazon CloudFront worldwide.
  • The talk covered the context and justification for QUIC, including the history of HTTP and latency issues, and how QUIC addresses these problems.
  • Mahmoud Raghab from Snapchat shared insights on how Snap tested and implemented QUIC, highlighting the importance of proper testing and analysis to ensure performance improvements.
  • The session concluded with a Q&A and a reminder to provide feedback on the session.

Insights

  • QUIC was developed with a focus on speed and user latency, aiming to provide faster and more reliable connections with fewer round trips.
  • The protocol was designed with insights from real-world internet behavior, rather than just theoretical models, which is crucial for its effectiveness.
  • QUIC's development was customer-obsessed and measurement-focused, aligning with Amazon's leadership principles.
  • The protocol addresses the limitations of previous HTTP versions and TCP/TLS by reducing round trip times, avoiding head-of-line blocking, and improving congestion control.
  • QUIC's support for HTTP/3 on Amazon CloudFront allows for better web performance, especially in congested networks.
  • Snapchat's case study provided practical insights into the deployment of QUIC, emphasizing the importance of thorough testing and data analysis when adopting new technologies.
  • The talk highlighted the collaborative effort between AWS and its customers to innovate and improve content delivery performance.
