Netflix uses a ๐บ๐ถ๐ฐ๐ฟ๐ผ๐๐ฒ๐ฟ๐๐ถ๐ฐ๐ฒ๐ ๐ฎ๐ฟ๐ฐ๐ต๐ถ๐๐ฒ๐ฐ๐๐๐ฟ๐ฒ where different functions are split into small, independent services. When you open Netflix, you connect through an Amazon Elastic Load Balancer (ELB) and API Gateway (Zuul) that directs your requests to the appropriate service. The content is stored in large cloud storage systems (like Amazon S3) and delivered through Content Delivery Networks (CDNs) placed worldwide to ensure fast streaming. This enables you to watch movies without hiccups, as they are streamed to you via the nearest geographical location.
Netflix's core consists of ๐๐ฒ๐๐ฒ๐ฟ๐ฎ๐น ๐ธ๐ฒ๐ ๐๐ฒ๐ฟ๐๐ถ๐ฐ๐ฒ๐ (๐๐ฃ๐๐). The Authentication service handles logins and security, while the User Profile service manages your preferences and watching history. The Content service (Play API) deals with all movie and show information, and the Recommendation service suggests content based on your viewing patterns. There's also a dedicated Search service to help users find content quickly.

All this data is stored in different specialized databases - some for user information, others for content metadata, and separate for analytics. The whole system is designed to be highly available and fault-tolerant, meaning that Netflix can continue working even if some parts fail.
The most impressive part is the scaleโNetflix can handle millions of users streaming content simultaneously, thanks to its extensive use of cloud services (primarily Amazon Web Services) and its globally distributed CDN network (Open Connect).
