Moreover, the blocking input/output tasks, such as accessing databases, is asynchronously processed via internal threads without interfering with the primary thread. These aspects of Node.js make it ideal for handling voluminous requests and run database operations. 
  • Microservices: Building microservices has been another key area where Node.js has been proved promising. The main driver behind Node.js adoption here is its nature of using event-driven architectures that can be decoupled. Node.js has been supporting many organizations in segmenting large scale systems into minute parts of microservices and deploying them independently. 
  • Real-Time Applications: Greater performance and deployment speed of Node.js make it ideal for use in real-time interactions. Such environments built with Node.js can allow the heavy traffic of numerous short messaging to flow in a streamlined manner. It can also be used for building applications that allow displaying messages to various users simultaneously. 

When to choose Java over Node.js for Application Development? 

Touted as the development of choice for web applications, Java is versatile and allows to develop resilient, customized solutions for all business requirements. Java is preferred among both small and large organizations alike, when it comes to software applications that are necessary to keep the business running. 

Following are some key application development areas where Java is essentially preferred.
