  1. Setting Up CloudFront Distributions: Create a CloudFront distribution and select your S3 bucket as the origin. This allows CloudFront to fetch and cache content from S3.
  2. Caching Strategies: Customize caching settings based on your content’s update frequency to optimize performance and reduce S3 access costs.
  3. Secure Content Delivery: Use signed URLs or signed cookies for controlled access to your S3 content.
