Describe your experience in developing and implementing microservice architectures.

In my experience of developing microservice architectures in Node.js, I participated in creating distributed systems where each service performs a separate business logic and interacts with others via APIs (usually REST or gRPC).

Key points of implementation:

• Dividing the application into independent services to improve scalability and support.
• Using Docker and Kubernetes for containerization and orchestration.
• Configuring communication between services via HTTP or messaging (e.g., RabbitMQ or Kafka).
• Implementing centralized logging and monitoring for tracking system status.
• Ensuring fault tolerance and load balancing.

Example of a simple microservice in Express:

const express = require('express');
const app = express();

app.get('/status', (req, res) => {
  res.json({ status: 'ok' });
});

app.listen(3000, () => console.log('Service running on port 3000'));

This approach allows flexible system development and scaling.
