What is Amazon CloudFront?

If your business is considering a migration to cloud-native or virtual servers and services, Amazon AWS is a leading choice among the “Big 3” cloud providers, offering unparalleled scalability and reliability. AWS services are designed to handle immense demand with ease.

For businesses with specific needs, such as delivering large files like videos or bulky media, finding a suitable solution is crucial. Opting for a provider that can’t meet these demands might result in poor customer experiences, particularly in an era where uninterrupted streaming media is expected.

To address the challenge of delivering large media files efficiently, Amazon developed CloudFront.

Amazon CloudFront is a content delivery network (CDN) designed to enhance the speed and efficiency of delivering web content. It operates through a globally distributed network of proxy servers, which cache and deliver larger media files, reducing latency and improving access speeds for users worldwide. CloudFront is a pay-as-you-go service offered by Amazon Web Services (AWS).

As of 2020, CloudFront operates from 205 edge locations across six continents, including regions in Europe, Asia, Australia, South America, Africa, and major U.S. cities. It routes user requests to the edge location that offers the best performance. If the requested content is not available at the nearest edge location, CloudFront retrieves it from a specified origin, such as an AWS bucket or a web server.

Beyond video files, CloudFront supports the delivery of entire websites, APIs, HTML, CSS, JavaScript, and images, making it a versatile tool for efficient content distribution.

A proxy server acts as an intermediary between a client requesting a resource and a server providing it. It translates traffic between networks or protocols and can:

• Enhance security
• Secure LAN activity
• Control website access
• Save bandwidth by caching files or compressing traffic

Unlike traditional proxy servers, CloudFront does not compress or alter content but accelerates delivery by moving content closer to users, minimizing latency.
