Amazon CloudFront is known as a web service that is meant to enhance the distribution speed of static & dynamic web content to your website visitors or business audience. For instance, it distributes web content such as .css, .js, image files, and .html files to the visitors or targeted audience.

AWS CloudFront uses edge locations for the distribution of these contents. The edge locations are the worldwide data center networks of CloudFront. The content that is being served with CloudFront, when requested, is routed to the edge location that has the lowest time delay or latency. It is done so that the content delivery can be done immediately for enhancing the performance of web apps or websites.

Setting up the AWS CloudFront for Delivering your Content

Setting up the AWS CloudFront for Delivering your Content

As you have now understood the brief definition of what is AWS CloudFront, you can now go ahead to know how does AWS CloudFront works. Here are the steps that you need to follow for setting up AWS CloudFront to deliver your content to the users.

  1. Firstly, you need to specify the origin server, such as S3 Bucket or HTTP server. These are the sources or servers from where CloudFront will extract the requested files. The origin servers are destined to store the original version of the files. After extracting the files, they will then be distributed to the users via respective edge locations.
  2. The files such as web pages, media files, and images are termed to be objects that need to be uploaded onto the origin servers. If you have picked Amazon S3 as your origin, then you need to enable the bucket to be read by all public. It will enable anyone with your CloudFront URL to access it. You can also give controlled access to the objects by making them private over the origin servers.
  3. Now, you will have to create a CloudFront distribution that connects CloudFront with the origin server for getting the files from it whenever the user puts up a request. Along with that, you can also enable the setting of allowing CloudFront to log the requests or let it process the requests immediately.
  4. Now, CloudFront assigns a specific domain name to all new distributions elaborated within the console that will be used to process the called requests.

Hence, in this way, you can set up the AWS CloudFront for processing the requests of delivering the web content to the users. It is the first step towards knowing how does AWS CloudFront work.
