When it comes to choosing the right tech for your next project or getting the performance and scalability precisely according to your needs, Node.js is the go-to choice for many industry sharks. It’s hard to resist the ubiquity, and vanilla simplicity Node.js performance offers. There are leading giants like Walmart, Paypal, Netflix, Uber, and many more who have benefited immensely from Node.js.

Node.js has been a knight in shining armor, saving web and mobile apps with its powerful performance. Wonder why Node.js is used for building scalable web apps ? Let’s find out the two important factors contributing to its success.

What is Node.js?

Node.js® is a JavaScript runtime environment built on Chrome’s V8 engine. It’s open-source, cross-platform, and lightning-fast for scalable web apps. Its event-driven nature with non-blocking I/O makes it the most popular runtime environment for handling high traffic network applications.

How Node.js offers Easy Scalability for Modern Applications

With a consistently growing consumer base of tens of millions of users, titans like Netflix, Walmart, Uber, Paypal, among others, have regarded Node.js as a viable solution for scalability.

The cutting-edge technology comes with tons of features like the cluster module. It facilitates load balancing over multiple CPU cores, making it easy to deliver desired outcomes through smaller modules without burning out the RAM process. Additionally, Node.js employs a non-blocking event-loop mechanism with high scalability and enables the server to process requests seamlessly.

From the development standpoint, Node.js allows you to leverage Microservices that further lets you segregate your application into smaller parts. This way, you get to define tasks and allocate them efficiently among different teams to fast-track development, deployment, and maintenance of each division of your application. Node.js and Microservic allow modern applications to scale up and down as per need and help companies achieve high performance with fewer resources.

For one, Walmart benefited enormously by replacing its former legacy system with the deadly combination– microservices architecture and Node.js. The retail giant saw an instant growth of 20% in overall conversions and a 98% boost in mobile conversion. What’s more, they ended up saving 40% of the computing power, but they also cut costs by a whopping 20-50%.

How Node.js offers High-performance for Real-time Applications

With Node.js, you can build supercharged applications that display results in the blink of an eye. Web applications powered by Node.js benefit massively from its ability to multitask. Unlike other platforms, its single-threaded, event-driven architecture processes multiple concurrent requests efficiently without clogging the RAM. Moreover, its event-loop and non-blocking I/O operations allow code execution at a pace which significantly impacts the application’s overall performance.

Node.js helped GoDaddy outperform its competition. While driving the SuperBowl ad campaign, the web hosting company was able to handle 10,000 requests per second with absolutely no downtime, utilizing only 10% hardware, all thanks to Node.js.

What fuels Node.js with this superpower is that it’s built on Google Chrome’s V8 engine and written in C++. It breaks Javascript functions into machine codes with high efficiency and speed. It matters because Google invests heavily in its engine to improve performance, security, and provide excellent support for modern JavaScript features. This directly impacts V8’s performance and, eventually, Node.js.

To ensure continuous advancements, Google has introduced the V8 benchmark suite to elevate Node.js’ performance with faster execution, better compilers, security patchworks, and ability to scale.

Closing Thoughts:

Developing web apps with robust tech is vital for companies to be future-ready, and that’s where Node.js enters the game. Over the years, Node.js has become the go-to tech to meet demands accurately for web app development. We are confident this article has helped you assess the scalability and performance factors that node.js offers.
