What is AWS CloudFront?

 Introduction To AWS CloudFront

AWS Cloudfront is one of the leading content delivery network services or CDN. The CloudFront is a popular service to provide web content management and distribution service with scalable features. It processes and distributes both static and dynamic web content along with video and application files with low latency and high transfer rates. In addition, AWS Cloud front distributes the content that is sourced from the Amazon S3 bucket store through regional centers known as edge locations.

The CloudFront service supports caching for faster web content delivery based on the content available on the CloudFront edge locations. There are several case studies available for implementing services specific to the media and entertainment industry. Some of the popular applications using AWS CloudFront are Amazon prime videos, Spotify, Hulu, and Sky News. It is also widely used for software distribution lifecycles.

How to Configure CloudFront to Deliver Content?

A CloudFront distribution needs to be created, which tells the CloudFront that from where your content would be delivered and other details like how to manage content delivery etc.

• Origin servers such as the Amazon S3 bucket needs to be specified. CloudFront accesses your files from these servers then distributes them globally through CloudFront edge locations.
• After specifying origin servers, upload your files to these origin servers. Files uploaded are called objects, and they can be web pages, media files, or others that can be served over HTTP.
• Then create a CloudFront distribution that would tell the CloudFront from which origin server it needs to access your files when users request them.
• Then the CloudFront assigns a domain name to the newly created distribution of yours, which would be visible in the CloudFront console.
• CloudFront sends the configuration of your distribution to all its edge locations, where copies of your objects are cached by CloudFront.

How is Content Delivered to Users by CloudFront?

After configuring CloudFront, user’s requests are handled as follows:

• Any user can access your application or website and can request objects required, like an HTML file or media file.
• When a request is sent by the user, Domain Name Server (DNS) sends or routes the request to the nearest CloudFront edge location or to an edge location that can best serve it.
• At the edge location, There can be two possibilities, i.e. whether files requested are in cache or not. If files are in the cache then CloudFront returns them to the user, and if files are not present in the cache, then:
• CloudFront compares the specifications in your distribution with the request. Then forwards the request to the origin server of your distribution, like the Amazon S3 bucket, for accessing the requested files.
• The origin server sends the requested files to the CloudFront edge location.
• When the first byte of the requested files arrives, CloudFront starts sending the files to the user.
• It also saves the files to the cache of CloudFront edge location so that it could be accessed easily in the future if the same or another user requests them.
