Amazon CloudFront Invalidation

  1. Create "Invalidation"
  2. Invalidation with API
Amazon CloudFront is a Content Delivery Network (CDN) that provides fast and secure delivery of static and dynamic web content to users around the world. CloudFront has a feature called "Cache Invalidation", which allows you to remove cached content from the CDN so that new content can be delivered to users.

2. Invalidation with API

CloudFront provides APIs that allow to create "Invalidation".
