## Resource

Lucas and Luna break down the architectural decisions behind Cloudflare's global edge network, which handles over 30 million HTTP requests per second. They explore how the company moved from a simple reverse proxy to a distributed system spanning 330 cities, the role of custom-built Nginx configurations, and the trade-offs between latency and consistency. Specific topics include the use of Anycast routing, the challenge of DDoS mitigation at scale, and how Cloudflare optimized its cache hierarchy for static content delivery. This episode is a deep dive for engineers and CTOs interested in high-performance networking and edge computing. #Cloudflare #EdgeNetwork #CDN #Anycast #DDoS #Nginx #Latency #Scalability #GlobalInfrastructure #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #CTO #Engineering #Architecture #Performance #Networking #Optimization Keep every episode free: buymeacoffee.com/fexingo
