Edge caching is relevant in the AWS Cloud computing. One, is to use Amazon CloudFront for edge caching your website. Use CloudFront to deliver website, such as dynamic, static, and streaming content using a global network of edge locations. CloudFront automatically routes requests for the content to the nearest edge location, so content is delivered with the best possible performance and within minimum time. CloudFront is used to work with other AWS services, like Amazon Simple Storage Service3 (Amazon S3) and Amazon Elastic Compute Cloud4 (Amazon EC2). CloudFront also works with any origin server that is not an AWS origin server, which stores the original, definitive versions of files. For CloudFront , there are no contracts or monthly commitments for using it–pay only for as much or as little content as you actually using through the service.
