Cloud Front

CloudFront is used as a global content delivery network (CDN). Cloud Front speeds up the delivery of your content through Amazon's worldwide network of mini-data centers called Edge Locations.

CloudFront works with other AWS services, as shown below, as an origin source for your application:

  • Amazon S3
  • Elastic Load Balancing
  • Amazon EC2
  • Lambda@Edge
  • AWS Shield

Tips

  • CloudFront is found under the Networking & Content Delivery section on the AWS Management Console.
  • Amazon countinously adds new Edge Locations.
  • CloudFront ensures that end-user requests are served from the closest edge location.
  • CloudFront works with non-AWS origin sources.
  • You can use GeoIP blocking to serve content (or not serve content) to specific countries.
  • Cache control headers determine how frequently CloudFront needs to check the origin for an updated version your file.
  • The maximum size of a single file that can be delivered through Amazon CloudFront is 20 GB.

What happens if the content is not found in the edge location when a user requests your application?
SOLUTION: Files are pulled from the origin

What is one reason you'd want to use Cloud Front?
