What is Amazon CloudFront?

Amazon CloudFront is a content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds. It integrates with other AWS services and uses edge locations worldwide to cache and serve content closer to end users. CloudFront supports both static and dynamic content delivery, provides DDoS protection through AWS Shield, and offers SSL/TLS encryption. It can serve content from S3 buckets, EC2 instances, Elastic Load Balancers, or custom origins. CloudFront also supports Lambda@Edge for running code at edge locations.
