What is CDN - Cloud Front and how does it help in cloud computing?

CloudFront is a global content delivery network (CDN) service that accelerates delivery of your websites, APIs, video content or other web assets. It integrates with other Web Services products to give developers and businesses an easy way to accelerate content to end users with no minimum usage commitments.CloudFront can be used to deliver your entire website, including dynamic, static, streaming, and interactive content using a global network of edge locations. Requests for your content are automatically routed to the nearest edge location, so content is delivered with the best possible performance. CloudFront is optimized to work with other Web Services, like Simple Storage Service , Elastic Compute Cloud , CloudFront also works seamlessly with any non-AWS origin server, which stores the original, definitive versions of your files. E.g. Amazon CloudFront.

A content delivery network (CDN) is a system of distributed servers (network) that deliver webpages and other Web content to a user based on the geographic locations of the user, the origin of the webpage and a content delivery server.

This service is effective in speeding the delivery of content of websites with high traffic and websites that have global reach. The closer the CDN server is to the user geographically, the faster the content will be delivered to the user. CDNs also provide protection from large surges in traffic.
