Amazon CloudFront

Amazon CloudFront is a content delivery network (CDN) service offered by Amazon Web Services (AWS). It delivers content, such as web pages, images, and videos, to users with low latency and high availability. While CloudFront isn`t specifically an advertising product or company, it can be used to deliver advertising content, such as banners and videos, to users more efficiently. Additionally, it can be integrated with advertising platforms to improve ad serving performance and user experience.
