Inside Netflix’s Architecture: Encoding, Open Connect & Chaos Engineering
Ever wonder how Netflix streams crystal-clear video to millions of people worldwide — in under a second? In this video, I break down Netflix’s core streaming architecture and react to how they solved some of the hardest engineering challenges on the planet.
We’ll cover:
⏩ Encoding & Transcoding – how Netflix prepares dozens of formats and bitrates in advance
⏩ Open Connect (Netflix’s DIY CDN) – why Netflix built its own global network instead of outsourcing
⏩ Real-Time Data (Kafka & Flink) – how every click and pause becomes telemetry that shapes your experience
⏩ Big Data Lakehouse – the S3 + Iceberg backbone that powers petabyte-scale analytics
⏩ Chaos Engineering (Simian Army) – why Netflix breaks its own systems on purpose to stay resilient
👉 Whether you’re a software engineer, cloud architect, or tech enthusiast, you’ll learn lessons about scalability, resilience, and owning the critical path.
🔔 Subscribe for Part 3 where we’ll go even deeper into Netflix’s engineering playbook.
