Why did Netflix move to Node.js ? (2024)

FAQs

Why did Netflix move to Node.js ? ›

Netflix initially used Node. js to enable high volume web streaming to over 182 million subscribers. Their three goals with this early infrastructure was to provide observability (metrics), debuggability (diagnostic tools) and availability (service registration). The result was the NodeQuark infrastructure.

Netflix runs on AWS. They started with a monolith and moved to microservices. Their reasons for migrating to microservices were the following: It was difficult to find bugs with many changes to a single codebase.

Netflix started out with the idea to make it easier and less expensive for people to watch movies. But they didn't want to stay in the DVD game forever. They had the foresight to predict that consumer behaviors would continue to shift. And, they wanted to stay ahead of the competition.

Node.

js has become integral to the success of applications such as Netflix, Uber, and PayPal due to its ability to handle high-performance, scalable requests with a non-blocking, event driven I/O model that allows it to manage multiple simultaneous connections effectively.

js 16 is at the end of its life, it just means it won't get updates after September 2023. But newer versions like Node. js 18 are still being worked on and updated.

Disadvantage #1: Microservices Are More Complex

Microservices involve a lot more moving parts than traditional applications, requiring enormous effort, careful planning, and strategically applied automations to ensure communication, monitoring, testing, and deployment processes run smoothly.

The journey began when Netflix decided to move from its own data centres to the public cloud. In 2008, Netflix was running relational databases in its own data centres when disaster struck. A data centre failure shut the entire service down and stopped DVD shipments for three days.

High Performance: Netflix is a scalable and robust app that can handle high traffic with ease. Moreover, there is no issue of poor functions. Netflix developers use Node. js to build a high-performant app, and it also allows real-time web app development.

With more than 6.3 million websites using Node. js, it has become the most widely used tool for web development in the United States. This statistic gives us a good outlook for the use of Node. js in 2024.

With tools like Express. js and Socket.IO, we quickly built robust and scalable streaming applications. Cost-Effectiveness: Node. js is open-source and free to use, which became a cost-effective option for building a streaming application for our client.

Is node js dead or not? ›

In 2023, Node. js remains incredibly popular, thanks to its outstanding features. Its winning combination of speed, scalability, and versatility doesn't just make it a player; it's a game-changer in web development. Developers love it for its features that make handling modern application development a breeze.

From my vantage point, Node. js isn't exactly losing its popularity; rather, it's entering a phase of normalization. It's becoming one of many viable options, rather than the go-to solution it once was.

Deno is a successor to Node. js, with the same creator, Ryan Dahl. This is a subreddit for discussing Deno and sharing projects built around it.

An advantage of microservices is the flexibility that allows different programming languages, structures, and environments to be used within the system. Thus, the system can be designed in such a way that all its parts have the best answer and performance possible.

The trouble is their tool, which was developed using microservices architecture, was never designed to scale. This approach was making their platform very expensive and creating bottlenecks, causing the team to step back, reassess their approach, and refactor things into a monolithic design.

In June 2024, Netflix's senior director of product, Patrick Flemming, discussed the switch to the new design, saying that the changes should help users cut down on the "gymnastics they do with their eyes".

The microservices architecture allowed Netflix to greatly speed up development and deployment of its platform and services. The company was able to build and test global services on a large scale without impacting the current system and they could quickly rollback if there were problems.
