Amazon CloudFront is a content delivery network (CDN) service that helps deliver data, videos, applications, and APIs to users with low latency and high transfer speeds. It works by caching content at various locations around the world, known as edge locations, which are closer to users. This reduces the distance data must travel, improving load times and overall user experience. CloudFront integrates seamlessly with other Amazon Web Services (AWS) products, such as Amazon S3 for storage and AWS Lambda for serverless computing. It also provides security features like SSL/TLS encryption and DDoS protection, ensuring that content is delivered safely and efficiently.
