A company hosts a static website on Amazon S3 behind Amazon CloudFront. The site uses a database backend. The site does not reflect recent updates from the Git repository. The CI/CD pipeline and webhooks indicate successful deployments to S3. What should a solutions architect do to ensure the site displays the updates?

The correct solution is to invalidate the CloudFront cache. When a static website hosted on S3 is accessed through CloudFront, CloudFront caches the content at edge locations to improve performance. If the S3 content is updated but the CloudFront cache is not invalidated, CloudFront will continue serving the old, cached version. Invalidating the cache forces CloudFront to fetch the latest content from S3. Adding an Application Load Balancer is unnecessary as the website is static and served via S3 and CloudFront. Adding ElastiCache would optimize database performance, but the problem states the issue is with website updates, not database access.
