In the ever-evolving landscape of web development, the shift towards cloud-native applications has become inevitable. Modern developers are continually seeking ways to build scalable, resilient, and efficient applications.

In this guide, we’ll explore the essential aspects of designing a cloud-native JavaScript application, with straightforward explanations and up-to-date code examples.

Embracing Cloud-Native Principles

1. Microservices Architecture

The foundation of any cloud-native application is a well-thought-out architecture. Embracing microservices allows you to break down your application into small, independent components. Each microservice is responsible for a specific business function, making it easier to scale and maintain.

// Example microservice definition in Node.js using Express
const express = require('express');
const app = express();
const port = 3000;

app.get('/api/users', (req, res) => {
  // Your microservice logic here
  res.json({ users: [] });
});

app.listen(port, () => {…
