Who wins the battle of technologies: Node.js vs Java?
Java is used to develop such applications as mobile apps (including Android), scientific applications, desktop GUI applications, middleware products, a wide range of web applications, including front and back office electronic trading systems and data processing projects. Java is the optimum technology for projects requiring a powerful language, able to handle large numbers of calculations, even at the cost of the longer application development process.
Node.js is suitable for “lighter” projects, however, development of applications requiring handling extensive amounts of data and calculations is possible as well, proven by numerous success stories. Among others, Node.js enabled PayPal’s software developers to double the number of requests served per second, while at the same time decreasing average response time by 35%.
Node and Java aren’t strictly the same and exact comparisons between these two, based only on benchmarks, won’t be conclusive. One of the key factors is the surrounding ecosystem and community support, and in this matters both Node.js and Java are perfectly backed due to their popularity and years of development. Also, comparing solely their performance, without a broader understanding of the process and concurrency models will not bring the answers you’re looking for. In order to find out which of these platforms will bring the most value for your project, you need to look further than just the performance – first, consider what type of application are you building. Then, mind the speed of application development (how fast do you want to get to the market?), the security of your product, and its scalability.
