Deploymern in aws

Deploying a MERN stack on AWS involves: React frontend on S3 + CloudFront, Node.js/Express backend on EC2 or Elastic Beanstalk, MongoDB on Atlas or DocumentDB. Use Nginx as reverse proxy and PM2 for process management.

Example

# Typical MERN deployment architecture:
# 1. Frontend: S3 + CloudFront (React build)
# 2. Backend: EC2 + Nginx + PM2 (Node.js API)
# 3. Database: MongoDB Atlas (managed)
# 4. Domain: Route 53 → CloudFront & EC2
# 5. SSL: ACM (free certificates)

This architecture separates frontend (static hosting) from backend (compute) for better scaling and cost efficiency.
