Node.JS has become an absolute necessity for clients considering they are saved from the trouble of managing the influx of users as the business expands.Node.JS is the perfect framework as it renders the biggest advantage of building scalable network applications quickly without much hassle. If horizontal scalable applications are what you are looking for, it is best to go for cloud services like Amazon Web Services (AWS) considering it’s easy to nail these applications through the auto-scaling and balancing features.Node.JS also poses a major challenge to PHP through its fast development and deployment in run time setup.

High Performance

Node.js uses the V8 javascript engine developed by google. The V8 engine is extremely fast. If you application does a lot of reading and writing to the internet or the filesystem, Nodejs is the fastest technology out there to build your application

Highly Scalable

Node.js works on a principle called the event loop unlike other tradition web application frameworks and this is what helps make it extremely scalable for realtime apps. So Scale is not something you worry about when you choose NodeJS

RealTime

Node.js excels in real time applications because of WebSockets. WebSockets are open 2-way communication channels between the client and the server. And this makes it really easy to build realtime applications like Games, Chat Engines, etc.
