🔹 Step 1: Prepare Your S3 Bucket

1. Go to: https://s3.console.aws.amazon.com/
2. Select or create a bucket.
3. Optional – if you want the files to be public (for direct access):
   • Go to Permissions tab.
   • Click Bucket Policy and add:

{
  "Version": "2012-10-17",
  "Statement": [{
    "Sid": "AllowPublicRead",
    "Effect": "Allow",
    "Principal": "*",
    "Action": "s3:GetObject",
    "Resource": "arn:aws:s3:::your-bucket-name/*"
  }]
}

Replace your-bucket-name with your actual bucket name.

🔹 Step 4: Configure Settings

• Viewer Protocol Policy: Redirect HTTP to HTTPS or HTTPS only (recommended)
• Cache Policy: Use recommended or select/create a custom one

🔹 Step 6: Access Files via CloudFront

Once deployed, your distribution will have a Domain Name, such as:
