What is required to set up a CloudFront distribution?

To set up a CloudFront distribution, it is necessary to create the distribution and specify the origin from which CloudFront will fetch the content, along with the various settings that govern the behavior of the distribution. This involves defining the type of content you'd like to serve (e.g., static or dynamic files) and outlining how CloudFront should handle caching, content expiration, and SSL settings. The origin could be an Amazon S3 bucket, an EC2 instance, or any other publicly accessible HTTP endpoint.

This process is central to the functionality of CloudFront, as it establishes the connection between CloudFront and the content sources. Without properly creating the distribution and specifying these elements, the CloudFront service cannot operate effectively.
