🚀 How to Deploy on AWS

1. 🎨 Upload Frontend to S3

• Create a new S3 bucket
• Enable static website hosting
• Upload index.html and scripts.js

2. 🗃️ Set up DynamoDB

• Table name: studentData
• Primary key: studentid (String)

3. 🐍 Create Lambda Functions

• Function 1: save_student.py
  ➤ Permission: dynamodb:PutItem

• Function 2: get_students.py
  ➤ Permission: dynamodb:Scan

4. 🌐 Setup API Gateway

• Create a REST API:
  • POST / → save_student Lambda
  • GET / → get_students Lambda
• Enable CORS for both

5. 🔒 Configure CloudFront

• Origin: S3 bucket
• Enable HTTPS
• Connect to domain (optional)
