The CTO Podcast with Fexingo · 2026-07-15 · 12 min
In this episode of The CTO Podcast, hosts Lucas and Luna dive into the technical architecture behind Netflix's Open Connect CDN. They explore how Netflix moved from third-party CDNs to building its own globally distributed appliance network to handle 4K HDR streaming at scale. Lucas breaks down the key design decisions: storing entire catalogs on SSDs at ISP edge locations, using predictive algorithms to pre-populate content, and the custom FreeBSD-based server hardware that achieves 90 Gbps per appliance. Luna discusses the trade-offs between peak throughput and storage density, and why Netflix prioritises consistent bitrates over burst speeds. They also touch on the open-sourcing of the Open Connect Appliance design and how it has influenced peer-to-peer CDN models. This episode offers a concrete look at one of the most ambitious edge infrastructure projects in streaming media. #Netflix #CDN #OpenConnect #Streaming #4K #EdgeComputing #ContentDelivery #VideoEngineering #FreeBSD #Infrastructure #TechArchitecture #CTO #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #TechnicalLeadership #EngineeringOrg #MediaEngineering Keep every episode free: buymeacoffee.com/fexingo
