CloudFront Origin Shield is an additional layer in the CloudFront caching cloud infrastructure that helps to minimize your origin’s load, improve its availability, and reduce its operating costs.
“Amazon CloudFront announces Origin Shield, a centralized caching layer that helps increase your cache hit ratio to reduce the load on your origin. Origin Shield also decreases your origin operating costs by collapsing requests across regions so as few as one request goes to your origin per object. You can also use Lambda@Edge with Origin Shield to enable advanced serverless logic like dynamic origin load balancing. Customers using Origin Shield for live streaming, image handling, or multi-CDN workloads have reported up to a 57% reduction in their origin’s load.”

Amazon CloudFront is a content delivery network (CDN) operated by Amazon Web Services. The content delivery network was created to provide a globally-distributed network of proxy servers to cache content, such as web videos or other bulky media, more locally to consumers, to improve access speed for downloading the content.
CloudFront has servers located in the United Kingdom, Ireland, The Netherlands, Germany, Spain, Hong Kong, Singapore, Japan, Taiwan, Vietnam, Indonesia, India, Australia, South America, Africa, and several major cities in the United States. In November 2022, the service operated from 400 edge locations on six continents.
CloudFront operates on a pay-as-you-go basis.
CloudFront competes with larger CDNs, such as Akamai, Azion, Cloudflare, and Edgio (previously known as Limelight Networks). Upon launch, Larry Dignan of ZDNet News stated that CloudFront could cause price and margin reductions for competing CDNs.
