Netflix's architecture, supporting 247 million subscribers, employs a client-backend-CDN system structure to ensure efficient streaming and exceptional user experience. Leveraging AWS for backend scalability, Netflix uses 700 microservices for modularity and ease of maintenance, and implements geographical redundancy for reliability. Through its custom CDN, Open Connect Appliance (OCA), and intelligent content delivery mechanisms, Netflix enhances streaming quality and performance. Additional strategies like efficient transcoding, predictive caching, DRM, and adaptive network handling further ensure a seamless experience across diverse devices and network conditions.
