Cloudflare Workers cloudflare architecture edge network anycast routing 100 million requests per second

Episode notes

Lucas and Luna dive into the architecture behind Cloudflare's global edge network, which handles over 100 million HTTP requests per second across 300+ cities. They explore how Cloudflare moved from a reverse-proxy model to a hyper-optimized, anycast-based infrastructure using custom-built servers, a proprietary operating system called Kernel by User (KbU), and a distributed key-value store called Quicksilver. The discussion covers how Cloudflare manages SSL termination at scale, mitigates DDoS attacks, and provides edge compute via Workers - all while maintaining sub-10ms latency. Specific numbers include 20 million Internet properties served, 100 Tbps of capacity, and a 50-microsecond p99 latency for Worker function cold starts. A must-listen for anyone interested in large-scale distributed systems and edge computing. #Cloudflare #EdgeComputing #CDN #Anycast #DDoSProtection #SSL #Workers #KbU #Quicksilver #DistributedSystems #Infrastructure #Latency #Architecture #TechLeadership #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #CTOPodcast Keep every episode free: buymeacoffee.com/fexingo
