Amazon CloudFront

Looking for a tool that delivers your user files, apps, and APIs safely, with low latency and fast transmission rates? And all in a developer-friendly environment? CloudFront is your solution.

What is Amazon CloudFront?

Amazon CloudFront is a fast content delivery network ( CloudFront CDN) service operated by Amazon Web Services (AWS). Amazon CloudFront is made up of a network of distributed servers at physical locations called “edge locations”. AWS CloudFront securely delivers data, APIs, videos, and applications to customers globally with low latency and high transfer speeds, all presented within a developer-friendly environment.


For the customer, Amazon CloudFront is a web service that speeds up the distribution of your static and dynamic web content – such as .html, .ss, .js, and image files – to your users. Simply put, Amazon CloudFront is a cloud computing infrastructure that is simple and easy to understand for the customer. When a user requests content that you’re serving with Amazon CloudFront, the request is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the highest possible performance.

How does Amazon CloudFront work?

When a user requests content that you’re serving with CloudFront, the request is routed to the CloudFront edge location that provides the lowest latency (time delay), so that content is delivered with the fastest possible performance.


Companies can use CloudFront for distributed videos and audio, but also for media-rich web applications, business dashboards, large amounts of data, or an API (Application Programming Interface). It’s suitable for both small start-ups and major organisations looking to distribute large video files around the world.

Can CloudFront Be Integrated With Other AWS Services?

CloudFront is able to use and integrate with a variety of AWS services as a data source for distribution, including but not limited to:


CloudFront can request files from an Amazon S3 bucket before placing them in edge locations. In addition to standard buckets, this also works with buckets that are configured as website endpoints. It is not necessary to modify the S3 bucket when CloudFront is configured.


CloudFront also enables the use of Amazon EC2 servers or Elastic Load Balancing endpoints as an origin for files used in CloudFront distribution. This integration is thanks to CloudFront’s support for custom HTTP/HTTPS origins, this also means it is possible to use a non-EC2 server as a file origin.

Safe & Secure Content Distribution With CloudFront

CloudFront offers the most advanced security capabilities, including field-level encryption and HTTPS support, seamlessly integrated with AWS ShieldAWS Web Application Firewall (WAF), and Amazon Route 53 to protect against multiple types of attacks including network and application layer DDoS attacks. These services co-reside at edge networking locations – globally scaled and connected via the AWS network backbone – providing a more secure, performant, and available experience for your users.

What Are The Benefits of Amazon CloudFront?

Amazon CloudFront provides serverless developers and businesses with a wide range of benefits including;


Simple Set-Up – Setting up CloudFront distribution is simple whether you’re using Amazon S3 or a custom HTTP/HTTPS endpoint as a file origin. Once set up, CloudFront requires no additional maintenance to continue working effectively, allowing you to focus on growing your business.


Scalability – CloudFront requires no configuration changes in order to respond to increased load as it automatically scales with the number of requests your files are getting. This makes CloudFront the perfect choice for serving the static content of your website or application.


Flexible Configuration – CloudFront distribution can be configured to fit your needs. Different caching policies can be set based on the kinds of content you are serving.

Examples of How Amazon CloudFront Can Be Used

Website Delivery and Security

Amazon CloudFront can speed up the delivery of your websites, whether its static objects (e.g., images, style sheets, JavaScript, etc.) or dynamic content (e.g., videos, audio, motion graphics, etc.), to viewers across the globe. The CDN offers a multi-tier cache by default that improves latency and lowers the load on origin servers when the object is not already cached at the Edge. With granular cache configuration controls, built-in capabilities such as gzip and brotli compression, access to geo-location headers, and edge compute capabilities, customers such as and Reach plc deliver content to millions of viewers. Integration with AWS Shield and WAF secures your website from network and application layer attacks while capabilities such as TLS 1.3 and Field-level Encryption offer improved security and performance.

Dynamic Content & API Acceleration

Accelerate and secure your dynamic content with Amazon CloudFront. Amazon CloudFront is used by customers, like Tinder and Slack, to secure and accelerate API calls as well as Websocket connections. CloudFront supports proxy methods (POST, PUT, OPTIONS, DELETE, and PATCH). TLS connections with clients terminate at a nearby edge location, and then CloudFront uses optimized network paths to securely reach your origins, with connection reuse available. If you use an AWS origin, traffic to the origin moves over AWS’s dedicated network backbone. AWS Shield and WAF protect your APIs at the CDN edge. Learn more about API Acceleration with CloudFront.

Live & On-Demand Video Streaming

CloudFront is designed to handle your live and on-demand video workloads. Benefit from the globally scaled and performant AWS network, private backbone connectivity to your AWS origins, and integration with AWS and Elemental Media Services. Further optimize your content delivery with default mid-tier caching, Origin Shield architecture, and real-time monitoring. CloudFront supports multiple streaming formats, including Microsoft Smooth, HLS, HDS, or MPEG-DASH, to any device. Additionally, integration with Elemental MediaStore offers low-latency streaming for a variety of sports, and game streaming use cases.

Software Distribution, Game Delivery, And IOT OTA

Amazon CloudFront scales automatically as your globally distributed clients download software updates. The software can be made available right at the edge in proximity to end-users, via the content delivery network. CloudFront’s high data transfer rates speed up the delivery of binaries, game patches, Internet of Things (IoT), and Over-the-air (OTA) updates – improving your customer’s experience cost-effectively at scale.
