Introduction To AWS CloudFront
Amazon CloudFront is a CDN (Content delivery network) service offered by AWS (Amazon Web Services). It can be integrated with other Amazon Web Services and provides developers a simple way to distribute their static or dynamic web content, videos, and applications to customers worldwide with high transfer speed and low latency.
AWS CloudFront is a web service that allows the user to distribute their content globally through regional centers also called edge locations. It helps to reduce latency (delay) as it ensures that content or data is delivered to the receiver through the nearest content data network (CDN) server. It is suitable for companies that need a rapid delivery of their content. Amazon CloudFront takes or accesses the data by using application programming interfaces from Amazon S3 and then places it in the regional data buckets.
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 Amazon S3 bucket needs to be specified. CloudFront accesses your files from these servers then distributed globally through CloudFront edge locations.
- After specifying origin servers, upload your files on 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 they are requested by users.
- Then the CloudFront assigns a domain name to the newly created distribution of yours, which would be visible in CloudFront console.
- CloudFront sends the configuration of your distribution to all its edge locations where copies of your objects are cached by CloudFront.
How Content is 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 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.
