Determine if CloudFront CDN is in use

CloudFront provides scalable, distributed, and inexpensive Content Distribution Network (CDN) within AWS. The use of a CDN can provide a layer of security between your origin content and the destination. It can also serve a critical role in consistent delivery of content during a DDoS attack or unexpected volume increases. This buffer can help give you the time to scale out your infrastructure to meet the demand and/or identify the origin to mitigate the risk if an attack. Ensure that AWS CloudFront Content Delivery Network (CDN) service is used within your AWS account to secure and accelerate the delivery of your website

Amazon CloudFront

Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, for example, .html, .css, .php, image, and media files, to end users. CloudFront delivers your content through a worldwide network of edge locations. When an end user requests content that you're serving with CloudFront, the user is routed to the edge location that provides the lowest latency, so content is delivered with the best possible performance. If the content is already in that edge location, CloudFront delivers it immediately.
