With the arrival of Node.js, #javascript has come to the forefront. It is likely to happen, since it is already a well-known programming language used by developers in browsers. And, with Node.js, it has found a way to implement the server side, thus reducing the complexity of using two different languages ​​at both ends.Today, Node.js offers one of the most innovative solutions for the creation of servers and web / mobile applications. Its single-threaded event loop and its asynchronous non-blocking input / output processing function distinguish it from other runtime environments. Its reach is rapidly increasing with valuable contributions from the community of developers and other giants of technology.At this time, several performance-based frameworks are being developed using Node.js (...)

Unfortunately, while Kubernetes can automatically keep your service up in the event of node failure or a software crash, it doesn’t actually know whether your service is behaving correctly. In fact, a service may be returning 500’s or taking too long to respond and the Kubernetes (...)

Node applications aren’t meant for handling 30k requests per second (in some cases they can, but only thanks to CPU and RAM).As we know Node is a single thread and doesn’t use the much resources of your machine (CPU, RAM).
