Amazon CloudFront is a rapid content delivery network (CDN) service that efficiently distributes data, videos, applications, and APIs to users worldwide with minimal latency and high transfer speeds, all within a user-friendly framework for developers. This CDN is closely integrated with AWS, utilizing both physical sites connected to the AWS global infrastructure and various other AWS services. It operates in harmony with offerings like AWS Shield for DDoS protection, Amazon S3, Elastic Load Balancing, or Amazon EC2 as the source for your applications, and Lambda@Edge, which allows you to execute custom code nearer to the end-users to enhance their experience. Notably, if AWS origins like Amazon S3, Amazon EC2, or Elastic Load Balancing are utilized, there are no charges for data transferred between these services and CloudFront. Moreover, you can tailor the code executed at the CDN edge using serverless computing capabilities, ensuring an optimal blend of cost efficiency, performance, and security while delivering content. This flexibility makes CloudFront an excellent choice for developers aiming to create a responsive and secure content delivery experience.
