The Basis of CDN Services
A CDN service, or Content Delivery Network service, is a technology that has been used since the early days of browser-based Internet access. Initially, CDNs could only serve or caching static content, such as images, video, CSS, and JavaScript. However, with advancements in CDN technology, it can also handle dynamic content. Dynamic content refers to non-cacheable elements of a website that require server-side or computational logic, such as user comments, shopping carts, and real-time data updates.

These distinct approaches impact how content is delivered and processed, influencing the overall performance of the CDNs.
Amazon CloudFront
CloudFront is Amazon’s offer for CDN with a much greater emphasis on distribution while offloading the need for security onto AWS’ security services. CloudFront is generally the better option if the aim is to distribute services as quickly as possible - especially if the service is already integrated with AWS infrastructure. Though the scale of CloudFront is generally more condensed, it has over three hundred access points across ninety cities in forty-seven different countries on top of partnerships with tier 1, tier 2, and tier 3 telecom carriers across the globe. As for local server computation, computing functionality is provided by CloudFront Functions and AWS Lambda.
While CloudFront does have a greater emphasis on distribution, that’s not to say the services that are based on it are vulnerable to attack. Amazon Route 53, AWS Web Application Firewall (WAF), and AWS Shield are all native options to AWS, and work against network-layer and application-layer attacks. CloudFront also utilizes SSL/TSL encryption and HTTPS protocols to ensure any data sent is protected. Under the circumstances of an attack and a server is forced offline or is down for maintenance, AWS does have redundancy functionality to ensure constant application uptime.
Finally, like other AWS services, CloudFront is designed to be incredibly cost-effective, able to shift whatever resources are required online and offline depending on activity. This ensures users only need to pay for what they need to use at that given moment.
