How Netflix Rebuilt Its CDN for 300 Million Subscribers -...

What this episode covers

Netflix's content delivery network, Open Connect, delivers over half of the world's internet traffic at peak. In this episode, Lucas and Luna dive deep into the specific architectural decisions Netflix made to scale its CDN from 100 million to 300 million subscribers. They explore the shift from commercial CDNs to a peered, ISP-embedded appliance model, the move from spinning disks to NVMe SSDs, and the caching algorithms that optimize for long-tail content. The hosts also discuss how Netflix manages the trade-off between cache hit ratio and storage cost, and why they chose to build their own hardware. This episode is a masterclass in infrastructure scaling from one of the most demanding streaming platforms on the planet. #Netflix #OpenConnect #CDN #ContentDeliveryNetwork #StreamingInfrastructure #VideoStreaming #EdgeComputing #CacheOptimization #NVMe #ISP #Peering #LongTailContent #CacheHitRatio #HardwareDesign #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #CTOPodcast Keep every episode free: buymeacoffee.com/fexingo
