Amazon CloudFront is a fast content delivery network (CDN) service that securely and with low latency and high speed delivers data, videos, applications, and APIs to global customers. The service also provides a developer-friendly environment.
Aimili Media Co., Ltd. is a media company with multimedia interaction and complementation, as well as resource integration. The company provides music, videos, and other content for free to audiences worldwide. Audiences can also access the content through the Aimili official website, applications, and social networks.
(1) Aimili hosts its domain name on Route53, a highly available and scalable DNS service. When devices like phones and computers access the custom domain, Route53 automatically routes the traffic to the nearest CloudFront PoP entry point.
(2) Multimedia content is divided into static and dynamic content. Static content like HTML and CSS can be stored directly on S3, while dynamic content needs to be generated by web servers.
(3) Based on the URL path, CloudFront forwards requests to either S3 or ELB, which has an auto-scaling group of web servers behind it.
(4) Locally produced videos and images are transmitted to AWS S3 over the internet via an IPSec VPN. This automatically triggers an S3 Event that invokes a Lambda function to extract frames and generate thumbnails for the videos.
