Each episode of The CTO Podcast with Fexingo examines a specific engineering leadership challenge — from scaling a microservices architecture without creating a distributed monolith, to managing the cognitive load of a 200-engineer org, to choosing between a monorepo and polyrepo strategy based on team topology. The conversations are grounded in real-world cases: how Etsy restructured its data pipeline after a 2019 outage, why Stripe’s API versioning policy reduces breaking changes, or what Basecamp’s choice of SQLite over PostgreSQL says about product philosophy. Lucas brings the journalistic rigor — citing commit histories, RFCs, and postmortems — while Luna pushes back with the pragmatics of org dynamics, hiring constraints, and technical debt. There are no hot takes, no vendor pitches, no ‘best practices’ without trade-offs. Each episode ends with a specific tension left unresolved: the optimal number of direct reports for a VP of Engineering, the point at which a monolith should be broken apart, or whether a platform team should own the CI/CD pipeline.

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","meta_description":"Netflix's content delivery network, Open Connect, delivers over half of the world's internet traffic at peak.
