How Netflix streams petabytes without buffering

from The Hitchhiker’s guide to how stuff works Hosted by Shoubhik Bose

Netflix manages its massive global streaming platform by dividing its infrastructure into two main systems: a control plane hosted on cloud servers that handles user browsing and account management, and a custom data plane that efficiently delivers video content locally through internet service providers. To prevent widespread outages, the company transitioned from a fragile monolithic application to thousands of autonomous microservices, utilizing dynamic service discovery and automated circuit breakers to isolate failures. Furthermore, the platform employs chaos engineering by intentionally breaking its own components during business hours to ensure system resilience, while massive data pipelines and machine learning models continually analyze user activity to personalize recommendations and optimize streaming quality.
