How Netflix builds the infrastructure to stream on every device

Netflix has developed a robust infrastructure to ensure seamless streaming experiences across a wide array of devices, driven by their commitment to enhancing customer satisfaction and fostering a culture of experimentation. The company's Device Management Platform, managed by the Partner Infrastructure Team, is pivotal in supporting this strategy by maintaining compatibility with numerous devices, such as smart TVs and streaming sticks from partners like Roku, Samsung, and LG. This platform employs a cloud-based automation framework called Netflix Test Studio to manage device testing, ensuring high streaming quality and user satisfaction. By leveraging technologies like MQTT, Kafka, and CockroachDB, Netflix achieves fault tolerance and horizontal scalability, crucial for managing device information and processing events. This infrastructure not only meets current demands but is also designed to scale with the growing number of devices and users, setting an industry standard for adaptive and future-ready application architectures.
