AWS CloudFront Invalidation

CloudFront invalidation tells AWS to remove cached copies of specified files from CDN edge locations so that CloudFront fetches the latest version from your origin (like S3) on the next request.

This is how you update files on the CDN before their normal TTL (Time to Live) expires. It’s critical for deployments that rely on caching or serve static files.
