In this Blog Post, We will try to elaborate the Comprehensive Guide on AWS Content Delivery Network called AWS Cloudfront.
Cloudfront, part of Amazon Web Services (AWS), is an AWS content delivery network (CDN) that provides fast delivery of media and files to customers over the Internet.
With Cloudfront, you can quickly and easily deliver your applications and video to end-users through a global network of edge locations with low latency and high transfer speeds.
AWS Content Delivery Network
Amazon Web Services (AWS) offers an online service that makes it easy to distribute content to end-users with low latency, high transfer speeds, and high availability.
It is called AWS Cloudfront, and it provides an easy-to-use CDN (Content Delivery Network) for video streaming, website hosting, and software downloads.
AWS Cloudfront is integrating with other Amazon Web Services products, such as S3 and Elastic Load Balancing, to give developers and businesses an easy way to accelerate content to end-users.

What Is AWS CloudFront?
Amazon CloudFront (previously known as AWS FrontEdge) is an easy-to-use content delivery network (CDN) offered by Amazon Web Services.
CloudFront operates on a pay-as-you-go basis which means, There are no contracts or setup fees.
For more information about pricing and plans, see Amazon CloudFront Pricing.
Free Usage Limits: When you sign up for Amazon CloudFront, we’ll start charging only when you exceed these usage limits.
If at any time during the month you exceed one of these limits and aren’t using a free usage tier, simply pay for additional capacity at regular rates.
Introduction To CDN Technology
A Content Delivery Network or CDN is a system of servers that work together to deliver the content requested by clients.
CDNs allow users from around the world to download files from local servers instead of central servers, providing increased download speeds, higher availability, and fault tolerance.
Any web page with static images, videos, or other media benefits from being served through a CDN.
Amazon has become one of many providers in offering customers their own Content Delivery Network for a very low cost.
They have several options starting as low as $3 per month! Check out how it works below!
Working With AWS CloudFront in Simple Terms
Amazon CloudFront is a fast and reliable service for viewing your static and dynamic websites online.
Also, it can decrease latency by caching copies of your files all over regions. So if someone from Oregon requests your website file, it will give them the fastest speed possible instead of loading directly from the server.
I have explained the basics of working with the AWS cloud front in simple terms.
Go through them one by one: Before you read- What is Amazon cloud front? Know what do you need before working with the AWS cloud front? Why use CDN when hosting on Amazon S3? How much does amazon cloud front cost? Is there any free usage limit available with AWS services like Elastic Load Balancing or Cloud Front?
Setting Up AWS Example
Setting up your Amazon Web Services account can be a bit of a chore. Luckily, there are plenty of easy-to-follow guides around that’ll walk you through setting up your account and using all of Amazon’s most powerful services, including S3 and EC2.
Once your setup is complete, give BitTorrent Sync a try – it syncs files between any devices connected to AWS, so if you upload something to your S3 account at home, for example, it’ll automatically show up on your work computer as well (and vice versa).
You won’t have to worry about manually synchronizing files between machines or losing data due to a crash.
Plus, since BitTorrent Sync uses HTTP or HTTPS connections instead of raw FTP connections, you don’t have to worry about leaving yourself vulnerable it’s faster than FTP with less data transfer overhead.

How To Configure/ Use/ Manage AWS CDN
Amazon CloudFront is a Content Delivery Network (CDN) that helps in delivering websites, web apps, and online content quickly by serving them from points of presence (PoPs) located closest to users. Amazon CloudFront follows a pay-as-you-go model.
The service is free for low volume data transfer and low latency requirements, while higher volume data transfer or latency-sensitive applications require paid plans.
These higher-level plans are called Beyond Free, as they are beyond what is offered with basic AWS accounts.
On all paid levels, there are options for 200% redundancy and automatic failover to another PoP if one fails; these features make Amazon CloudFront suitable for use with high availability (HA) services such as those provided by other cloud providers.
Using Amazon CloudFront requires no knowledge of DNS management or networking because it relies on existing infrastructure.
Advanced Topics In Using AWS CDN
There are two types of cloud hosting services: static and dynamic. Static cloud hosting service allows users to host static files on a server.
While Dynamic cloud hosting service is specifically designed for more dynamic files such as HTML5, PHP, and CGI.
A Content Delivery Network (CDN) is a collection of servers deployed in multiple data centers throughout a region that work together to provide a fast content delivery network on behalf of a single website or application.
In simple terms, a CDN serves as a proxy between your web application/website and your end-user.
It is used mainly to cache frequently accessed content and eliminate latency.
Let’s discuss AWS CDN in detail with respect to its features and use cases.
Recommendations from professionals who have implemented AWS CDN Solutions: I recommend using Amazon S3 Bucket with HTTPS enabled endpoint when configuring Amazon CloudFront distribution.
AWS Cloudfront Distribution
This is used for static content and supports browsers and mobile devices. To set up a distribution you need to create: DNS records, an origin server, and a Cache Behavior.
You can select a default cache behavior, or you can define custom cache behaviors for your distribution.
CloudFront stores copies of your files in multiple edge locations around the world and serves them to viewers who request them using HTTP or HTTPS from the Internet.
It’s important to note that if you use CloudFront over SSL (HTTPS), then only customers with valid SSL certificates will be able to access your website.
However, if you don’t use SSL on your website then anyone will be able to access it.
AWS Cloudfront Pricing
Amazon offers free usage of its cloud storage service to any user. This means you can use up to 5GB of Amazon S3 storage space and still enjoy a free tier if you’re only using it for your personal projects.
If you’re storing media files, we recommend choosing one of their two storage options: $0.03 per GB-month if your content is less than 50GB, or $0.022 per GB-month if it’s over 50GB. You will need an AWS account in order to use CloudFront and S3.
The Service Terms for CloudFront include Acceptable Use Limitations designed to protect our users from inappropriate or abusive uses of our Services, including improper file sharing.
AWS Global Accelerator vs Cloudfront
What’s the difference? The Amazon Web Services Global Accelerator (AWS G-AC) helps reduce bandwidth costs for moving large amounts of data across international borders.
It accelerates outbound data transfers from Amazon S3 buckets in all regions except for US Standard and operates at no additional charge.
This is done by passing requests for those objects through a set of points called Edge Locations, which are located near major transit points around the world and make direct connections back to Amazon S3 in either North America or Europe.
Troubleshooting Tips for AWS Cloudfront
Though it’s rare, sometimes your content delivery just isn’t working. Here are some troubleshooting tips you can use when you find that CloudFront is being disobedient.
1.) Use Fiddler to confirm requests are reaching CDN.
2.) Check if security groups aren’t allowing traffic; make sure health checks on backend servers indicate they have connectivity
3.) Check-in with S3 or Route 53 records; if there’s a change in configuration and re-deploy
4.) Dig into access logs of primary service (Cloudfront) – go through each one and check for clues
5.) Reach out to support!
AWS-hosted content delivery network (AWS CloudFront) is a Web service that delivers content using a global network of edge locations.
A CDN works by caching copies of content, so that each visitor requesting a resource is first directed toward an edge location in their geographical vicinity, reducing the load on origin servers and improving overall access speeds.
In addition to accelerating websites and web applications, CDNs provide comprehensive security services.
