When you connect to Netflix you connect to two different platforms, 1) Amazon Web Services: Netflix has long been a user of various AWS services. Amazon Web Services( AWS), is the section of the Amazon company that sells cloud computing services to both the outside world and to Amazon itself. You can purchase storage space to hold a huge database, bandwidth to host a website, or processing power to run complex software remotely.
Amazon Cloud: Initially, Netflix had its own data centers, however, after major database corruption, the company began to look out for good cloud computing services and settled for the AWS Cloud. The AWS Cloud offers the greatest ability to scale, which is critical for a business growing at their pace, along with the greatest portfolio of services.
2) Netflix OpenConnect-- Netflix built its own dedicated Content Delivery Network for serving video bits. Netflix used to rely on third-party providers like Akamai and Level 3 for the caching work, but it now delivers all its content via OpenConnect.
The content is carried by local ISPs( Internet service providers) who connect to the CDN(
Content Delivery Network) in one of two ways: they peer with it at common Internet exchanges— basically big data centers where different network providers connect to each other— or they can install Netflix ' s storage systems, which it provides them for free, on their own premises. Either way, doing so reduces the strain of Netflix traffic going over their networks.
