Amazon CloudFront is a global content delivery network (CDN) service that securely accelerates the delivery of websites, applications, videos, large files, and APIs to your viewers around the world. In general, Amazon CloudFront can be configured in conjunction with different types of origins from which it will fetch your content. When you configure an AWS origin, you benefit from:
Cost optimization: Data transfer out costs from an AWS origin to CloudFront Edge Location is free of charge.
Improved performance: Connections to other parts of AWS are made over high-quality networks that are monitored by Amazon for both availability and low latency. This monitoring has the beneficial side effect of keeping error rates low and window sizes high.
