Which AWS service would you use to improve content delivery?

Amazon CloudFront is a content delivery network (CDN) service that significantly improves the delivery of your static and dynamic web content, such as HTML, CSS, JavaScript, and images, to users globally. By caching content at edge locations that are geographically closer to users, CloudFront reduces latency and speeds up the load time of websites and applications.

This service optimizes the delivery process by serving cached content whenever possible and dynamically delivering content that isn't cached. Additionally, it integrates seamlessly with other AWS services, such as Amazon S3 for static file storage and Amazon EC2 for computing resources, enhancing the overall performance of web applications.

The other services mentioned serve different purposes: Amazon S3 is primarily for object storage, Amazon EC2 provides compute capacity in the cloud, and Amazon RDS is focused on managed relational database services. While these services can be components of a web application architecture, they do not directly enhance content delivery in the same way that CloudFront does.
