AWS Services Used

Service	Purpose
Amazon S3	Static file hosting (private bucket)
Amazon CloudFront	CDN, HTTPS termination, global edge caching
AWS ACM	Free SSL/TLS certificate for custom domain
AWS IAM	Scoped credentials for GitHub Actions
GitHub Actions	CI/CD pipeline — auto-deploy on push

Key Cloud Concepts Demonstrated

Private S3 + OAC — Bucket is fully private; CloudFront accesses it via Origin Access Control (OAC), the modern replacement for OAI
CDN edge caching — CloudFront serves cached content from global edge locations for low latency worldwide
HTTPS everywhere — ACM-issued SSL certificate attached to CloudFront; HTTP auto-redirects to HTTPS
Custom domain — .tech domain pointed to CloudFront via CNAME; root domain forwarded to www subdomain
CI/CD pipeline — GitHub Actions automatically syncs S3 and invalidates CloudFront cache on every git push to main
Cache invalidation — /* invalidation ensures visitors always get the latest version after each deploy
Least privilege IAM — GitHub Actions uses a dedicated IAM user with only S3 and CloudFront permissions

CI/CD Pipeline

Every push to main in the private portfolio repo triggers the following workflow:

name: Deploy StaticEdge to S3 + CloudFront

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Configure AWS credentials
        uses: aws-actions/configure-aws-credentials@v2
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: ${{ secrets.AWS_REGION }}

      - name: Sync files to S3
        run: |
          aws s3 sync . s3://${{ secrets.S3_BUCKET }} \
            --delete \
            --cache-control "max-age=86400" \
            --exclude ".git/*" \
            --exclude ".github/*" \
            --exclude "README.md"

      - name: Invalidate CloudFront cache
        run: |
          aws cloudfront create-invalidation \
            --distribution-id ${{ secrets.CLOUDFRONT_DISTRIBUTION_ID }} \
            --paths "/*"
