CloudFront is a global AWS managed Content-Delivery-Network (CDN). Invalidation of a CloudFront asset forces TTL to be timeout immediately. This causes fresh origin request for next CloudFront request for a specific asset (static file, html content).
Preconditions
To invalidate your CloudFront-CDN on your own, request the access permissions by sending an E-Mail to service@root360.de or creating a ticket in the ticket system.
