Building Scalable Microservices with Node.js and Docker

# Building Scalable Microservices

Microservices architecture has become the go-to approach for building scalable and maintainable applications.

## Why Microservices?

- **Scalability**: Scale individual services independently
- **Flexibility**: Use different technologies for different services
- **Resilience**: Isolated failures don't bring down the entire system

## Getting Started with Docker

Docker makes it easy to package and deploy microservices consistently across different environments.

## Best Practices

1. Keep services small and focused
2. Use API gateways
3. Implement proper monitoring and logging
4. Design for failure

## Conclusion

Microservices aren't a silver bullet, but when done right, they can significantly improve your application's scalability and maintainability.
