• collection of microservices (which means that each application, or microservice’s code and resources are it’s very own)
• store high-quality content on AWS servers.
• another set of AWS servers are responsible for converting the movie for different devices, different internet connection. This is called transcoding.
• in order to reduce the load times, CDN is used. What CDNs basically do is, they take the original website and the media content it contains, and copy it across hundreds of servers spread all over the world.
• in order to deliver higher number of content at more locations while lowering costs — and this led them to build their own CDN, called Open Connect.
• Netflix strikes deals with internet service providers and provides them the red box you saw above at no cost. ISPs install these along with their servers. These Open Connect boxes download the Netflix library for their region from the main servers in the US — if there are multiple of them, each will rather store content that is more popular with Netflix users in a region to prioritise speed.
