Cloudfront is a content delivery network (CDN) provided by Amazon Web Services (AWS). It is used to distribute web content globally to end-users with low latency, high data transfer speeds, and high availability.

In this post, we will dive deep into the world of AWS Cloudfront and explore its key features, benefits, and use cases.

What is Cloudfront?

Cloudfront is a web service that makes it faster to distribute HTML, CSS, JavaScript, and images, as well as other types of static and dynamic web content. It works with other Amazon Web Services to give businesses and developers a full solution for delivering web and mobile content.

With AWS Cloudfront, content is delivered to end users from a network of edge locations that are closer to them. This cuts down on latency and makes the user experience better.

How AWS Cloudfront uses Edge Locations to distribute content

AWS Cloudfront uses its edge locations to distribute content globally, ensuring users can access content quickly and efficiently.

When a user requests content, Cloudfront checks the closest edge location to see if the content is cached. If it is, the edge location serves the content to the user, reducing the time it takes to load. If the content isn’t cached, Cloudfront fetches it from the origin server and caches it at the edge location for future requests.

By using Cloudfront and its edge locations, businesses and online platforms can improve website speed and enhance user experience. This can help drive engagement and increase conversions, leading to improved business results.

Getting Started with AWS Cloudfront

Getting started with Cloudfront is simple and straightforward.

To get started, you will need to sign up for an Amazon Web Services (AWS) account and create a new Cloudfront distribution.

This involves specifying the origin of your content, the behaviors you want to apply to your content and the distribution settings.

1. Log in to the AWS Management Console.
2. Go to the Cloudfront dashboard.
3. Create a new distribution.
4. Choose the type of distribution you want to create.
5. Set up the origin server where your content is stored.
6. Configure the edge locations you want to use.
7. Choose the default cache behavior.
8. Deploy your distribution.

Once your distribution is set up, you can monitor its performance and make changes as needed to optimize your content distribution and website performance. It’s important to regularly review your Cloudfront configuration and make updates as needed to ensure optimal performance.

Testing the Links

After creating distribution, Cloudfront knows the location of Amazon S3 server and the user knows the domain name associated with the distribution. However, we can also create a link to Amazon S3 bucket content with that domain name and have Cloudfront serve it. This helps save a lot of time.

Following are the steps to link an object:

Step 1 − Copy the following HTML code to a new file and replace domain name with the domain name that Cloudfront assigned to the distribution. Replace object-name with the file name of an Amazon S3 bucket.

<html> 
   <head>Cloudfront Testing link</head> 
   <body> 
      <p>My Cloudfront.</p> 
      <p><img src = "http://domain-name/object-name" alt = "test image"/> 
   </body> 
</html>

Step 2 − Save the text in a file with .html extension.

Step 3 − Open the web page in a browser to test the links to ensure they work properly. If not, double-check the settings.
