Amazon CloudFront

Leading global CDN provider as part of the AWS ecosystem, one of the top three CDN services worldwide by market share

Amazon CloudFront is a fast content delivery network (CDN) service offered by Amazon Web Services (AWS) that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. Launched in 2008, CloudFront integrates deeply with other AWS services and uses a global network of edge locations to cache and serve content closer to end users. The service operates within Amazon's broader cloud infrastructure ecosystem, serving millions of websites and applications worldwide. While CloudFront is primarily infrastructure-focused rather than pure AdTech, it plays a critical role in the advertising technology ecosystem by enabling fast delivery of ad creative, video ads, and tracking pixels. Publishers, ad networks, and demand-side platforms rely on CloudFront to ensure low-latency delivery of advertising content and real-time bidding responses. The service supports dynamic content delivery, streaming media, and API acceleration, making it essential infrastructure for programmatic advertising platforms that require millisecond-level response times. As a subsidiary service of Amazon Web Services, CloudFront benefits from Amazon's massive global infrastructure investment and continuous innovation in edge computing. The service competes directly with other major CDN providers while offering unique advantages through its tight integration with AWS's comprehensive cloud services portfolio, including S3 storage, Lambda@Edge for serverless computing at the edge, and AWS Shield for DDoS protection.
