Single Threading

Traditional web-serving techniques use each connection (request) to spawn a new thread (the time and resources to execute a small unit of instructions). This takes up system RAM and eventually maxing-out at the amount of RAM available.

Popular use case opportunities in Node.js

Node.js stands out for its speed, intensive data exchange, application scalability, etc. and that is why it has been used by NASA, Netflix, Paypal and other companies.

1. Chats/Chatbots:

The chat application is a popular example of Node.js. It helps in creating a data-intensive (but low processing/computation), high traffic, lightweight application that runs across distributed devices.

2. Microservices:

When building and deploying microservices solutions, Node.js is the technology of choice. Companies are using two frameworks for microservice architecture. The restify is used by npm and Netflix, while the Express framework lists Uber and IBM among its users.

3. Data streaming

Netflix chose Node.js for application scalability and intensive data exchange.

4. Real time data

There is a need to plan out extra resources to execute all the operations without failing to meet any service-level agreements if your web app is running live 24 x 7.

Wrapping Up

In conclusion, if your use case does not access any blocking resources nor contain CPU intensive operations, you can exploit the benefits of Node.js and enjoy scalable and fast network applications.
