*Overall Architecture Diagram:

Client (Browser) --->(with HTTP Request)---> S3 Bucket (Frontend - React) ---> API Gateway --->

EC2 (Node.js Backend)Instance ---> RDS (PostgreSQL)

1-Docker Architecture:

Docker Container: ┌────────────────────────────┐ │ App (Node.js + Express) │ │ │ │ Exposes Port 3000 │ │ Connected to PostgreSQL DB │ └────────────────────────────┘

docker-compose.yml maps:

-Host port 3000 to container port 3000 -Image is shadi38/node-app:4.0

2-CI/CD Pipeline (GitHub Actions):

-Frontend CI/CD: GitHub → GitHub Actions: ├── Checkout Code ├── Install Dependencies ├── Build React App └── Upload to S3 (Bucket: recommendationsh)

-Backend CI/CD (Node.js) GitHub → GitHub Actions: ├── Build Docker Image ├── Push to DockerHub (shadi38/node-app:4.0) ├── Connect to EC2 via SSH │ ├── Stop & remove old container │ ├── Pull latest Docker image │ └── Run new container with .env file

3-Terraform Structure:

Terraform Scripts: ├── AWS Provider ├── EC2 Instance for Backend ├── Security Group (port 22 & 3000) ├── S3 Bucket for Frontend └── RDS PostgreSQL setup
