What does Amazon CloudFront improve for users?

Amazon CloudFront is a content delivery network (CDN) service designed to accelerate the delivery of web content, including static and dynamic files like HTML pages, CSS stylesheets, JavaScript files, and images. It achieves this by caching content at strategically located edge locations around the world. As users request content, CloudFront serves it from the nearest edge location, which significantly reduces latency and improves loading times. This enhanced performance is especially beneficial for applications with global audiences, as it ensures that users have quicker access to content regardless of their geographic location.

This focus on fast, reliable content delivery is what differentiates CloudFront and highlights its role in improving user experiences by enhancing content delivery speeds globally. The other options—virtual machine deployment, database query efficiency, and development lifecycle management—are not directly related to the core functionality of Amazon CloudFront, which specifically targets the optimization of content delivery rather than infrastructure management or application development processes.
