Explanation
Using a single CloudFront distribution with caching and tuned TTLs improves global performance by serving content from edge locations and reduces load on the S3 origin. Enabling Origin Shield further reduces origin load by adding an additional centralized cache layer, and configuring origin failover to a second S3 bucket in another Region provides high availability. S3 replication keeps the failover bucket in sync across Regions with minimal operational effort.
