Amazon CloudFront

Leading global CDN provider as part of AWS, one of the top three CDN services worldwide

Amazon CloudFront is a content delivery network (CDN) service operated by Amazon Web Services (AWS). It integrates with other AWS services to provide developers and businesses with an easy way to distribute content to end users with low latency, high data transfer speeds, and no minimum usage commitments. CloudFront uses a global network of edge locations to cache and serve content closer to viewers, reducing latency and improving performance. While CloudFront is primarily an infrastructure service rather than a pure AdTech platform, it plays a critical role in the AdTech ecosystem by enabling fast delivery of ad content, creative assets, video ads, and analytics data. Many AdTech companies and publishers use CloudFront to serve ad impressions, deliver programmatic advertising content, and ensure low-latency delivery of rich media advertisements. The service supports real-time bidding environments where milliseconds matter and provides the scalability needed for high-traffic advertising campaigns. CloudFront's integration with AWS's broader ecosystem, including S3 for storage, Lambda@Edge for edge computing, and AWS Shield for DDoS protection, makes it a foundational component for companies building AdTech infrastructure. Its global presence with over 400 points of presence across 90+ cities ensures that advertising content can be delivered quickly to audiences worldwide, which is essential for maintaining user experience and ad viewability metrics.
