Node.js provides lots of advantages when it comes to scalability. It allows just one server to handle hundreds of times more clients than one running traditional server technologies, making it a highly scalable and attractive solution in today’s web application market.
Node.js uses the websocket protocol that provides a real time power. It takes care of multi user requirement, real time web applications like chat and games. Websockets are simply two-way communications channels between the client and server.
The popularity of Node.js web and mobile development is growing rapidly and it consists of wide support and resources available. Also, developers seem to really love it and a happy developer is a developer you want to have.
Node.js architecture helps us to overcome performance and scalability problems due to its non-blocking interaction. Due to its high performance we can avoid costs for extra hardware. Node.js used at the centre of complex transactional systems, where real time responses for multiple requests are required. By using Node.js, web applications can be developed in a short time.
