In this blog on Amazon CloudFront, we will read in detail about the following topics:

Check out this insightful AWS Tutorial to get you started: 

Let’s begin by understanding what Amazon Cloudfront is and how it delivers content to its users.

What is AWS Cloudfront?

Amazon Cloudfront is a content delivery network (AWS CDN) that retrieves data stored in the Amazon S3 bucket and distributes it to numerous edge locations across the world. Edge locations are the network of data centers distributed worldwide through which content is delivered.

Amazon CloudFront Working

When a user requests content that is being served with CloudFront, the request is routed to the nearest edge location that gives the lowest latency. This helps the user to access content with the best possible performance. The Amazon cloud architecture functions as follows.

  • If the content is already cached in the edge location, CloudFront delivers it immediately with the lowest latency possible.
  • If the content is not present in the edge location, CloudFront retrieves it from the origin (like Amazon S3 bucket, a MediaPackage channel, or an HTTP server) that has been identified for your content.

Let’s now look at Amazon CloudFront and understand how it delivers content from the origin to the end-user.

How does Amazon CloudFront deliver content?

Once an Amazon S3 Bucket or HTTP Server is set up, a CloudFront distribution is created to tell CloudFront where you want the content to be delivered and details about tracking and managing content delivery.

CloudFront then uses edge servers that are close to your viewers to deliver content quickly when someone accesses it.

How does Amazon CloudFront deliver Content?

Steps to configure CloudFront to deliver content : 

  1. When the origin servers such as the Amazon S3 bucket or an own HTTP server are specified, CloudFront gets the required files which are then distributed from CloudFront edge locations all over the world. 
  2. Files are uploaded to the origin servers. The files also known as objects, typically include web pages, images, and media files. It can include anything that can be served over HTTP.
  3. The CloudFront distribution tells CloudFront which origins to get the files from when users request the files through the website or application.CloudFront also logs all the requests and distribution can be enabled as soon as it’s created. 
  4. A domain is assigned to the new distribution that can be found in the CloudFront console or an alternate domain can be used instead.
  5. The distribution is sent across to all the edge locations or points of presence collections that are collections of servers in geographically dispersed data centers where CloudFront caches a copy of the data.

Now, let’s take a look at a few important terminologies used throughout this blog. It will help you understand the topics with more clarity.

Key Terminology in AWS CloudFront.

Edge Locations: A worldwide network of data centers that deliver content to the end-user are called edge Locations.

Latency: It is a measure of delay or time data takes to get to its destination from the source point. 

Amazon Content Delivery Network (AWS CDN): A content delivery network (CDN) represents a group of servers that are geographically distributed over the globe and provide a fast delivery.

Amazon S3 Bucket: An Amazon S3 bucket is a public cloud storage resource available in Amazon Web Services.

Origin Access Identity: An Origin Access Identity (OAI) is used for sharing private content via CloudFront. The OAI is a virtual user identity that will be used to give your CF distribution permission to fetch a private object from your origin server (e.g. S3 bucket).

Since now you are familiar with the key terminology, let’s move on to the benefits of CloudFront.

Benefits and Features of AWS CloudFront

  • Globally

There are 216 edge locations across the globe. With the number of edge locations, it enables the end-user to use your content without any latency.

  • Fast 

Amazon CloudFront provides a high data transfer rate since the content is already cached in the nearest edge location, it gives the end-user a lightning-fast speed delivery of the content. 

  • Dynamic Transfer

It provides an option for both static and dynamic content delivery. As soon as one byte is loaded into the cache, it is immediately transferred to the client working as a Live Steam.

  • Encryption

A highly secure application is developed without extra cost. A CloudFront inherits the features of AWS Shield Standard. The edge locations which are spread across the globe feature a 7 Layer Protection named AWS Web Application Firewall. 

  • AWS Integration

The whole of AWS-supported services for your content or application can be integrated into the CloudFront.

Static asset caching

By using CloudFront, the advantage of AWS backbone can be obtained for your application. CloudFront gives your end users a fast, safe, and reliable experience.

Amazon S3 Bucket can be used as a simple approach for storing and delivering static content. When S3 is used together with CloudFront, an option to use Origin Access identity (OAI) can be used to easily restrict access to your S3 content.

Live Streaming

Live Streaming for AWS CloudFront

Both pre-recorded and live events can be streamed to global viewers. 

  • Formats such as MPEG DASH, Apple HLS, Microsoft Smooth Streaming, and CMAF can be streamed using the CloudFront for the Video on Demand (VOD) streaming service.
  • For live streaming, media fragments are cached at the edge, so the multiple requests for the manifest file which delivers the fragments in order can be combined. This method reduces the load on the origin server.
