There are various strategies you can employ to build your own streaming platform. These are some of the strategies used by the most successful streaming service, Netflix:
The idea behind a content distribution network is to put content as close as possible to the users. When the user requests a video, the app will find the nearest server with the video. The app then streams the video from there to the device. The most significant benefits of CDN are speed and reliability. By moving the video source as close as possible to the people watching it, the viewing experience will be much faster and reliable.
Along with the optimization of page content and libraries, the use of CDN also ensures that the application has a faster load time. It loads content from the nearest location of the user. The use of AWS Cloudfront can make a significant difference in terms of loading speed along with supporting caching strategy.
Some streaming services even start their own CDNs, but this can only be done if their video catalog is small enough. If the videos are lesser, one location can store all content. As companies grow, building their CDN makes even less sense. Third-party CDNs allow them to have a global reach instantly using existing services. By outsourcing their distribution networks, services get more time to work on higher priority projects. They can utilize this time to create algorithms to adapt to changing network conditions.
In 2012, Netflix launched its dedicated CDN solution to maximize network efficiency. Its own purpose-built CDN has proven to be very advantageous for Netflix. Open Connect is less expensive compared to other third-party distribution networks. It allowed them to control the entire video path. They now have control over transcoding, CDN, and clients. It has also made the app more scalable. Higher scalability is in line with Netflix’s goal of offering its service the world over. Their CDN allows them to know who their users are. They even have their own computer system for video storage called OCA (Open Connect Appliances). This helps Netflix make various optimization choices other services cannot make. Their high-performance CDN has allowed them to deliver a superior video viewing experience.

The total cost of development of a Netflix like app ranges between $150000 to $250000. This cost includes the iOS application development, the Android application, back-end, and front-end development. A lot of work goes into the optimization of streams and building scalable architecture. DevOps practice is required to make optimized use of storage and retrieval services.
How to build a streaming service like Netflix, an on-demand app, runs on a microservices architecture. To simply put this, each application is, the microservice’s code, and its resources, are on its own. There is no basis of sharing that one can expect or observe. If multiple applications wish to interact, that will happen only via APIs.
