# Building Scalable Microservices with Node.js and Docker
Microservices architecture has become the go-to approach for building scalable, maintainable backend systems. In this guide, we'll explore how to build production-ready microservices with Node.js and Docker.
## Why Microservices?
Traditional monolithic applications become difficult to scale and maintain as they grow. Microservices solve this by breaking down the application into smaller, independently deployable services.
## Setting Up the Foundation
### Docker Compose Setup
```yaml
version: '3.8'
services:
api-gateway:
image: nginx:latest
ports:
- "80:80"
user-service:
build: ./user-service
environment:
- NODE_ENV=production
```
## Best Practices
1. **Single Responsibility**: Each service should do one thing well
2. **API-First Design**: Define contracts before implementation
3. **Health Checks**: Always implement health check endpoints
4. **Circuit Breakers**: Prevent cascade failures
