What is Amazon CloudFront primarily used for?

Amazon CloudFront is primarily used for content delivery with low latency and high transfer speeds. It is a global content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers worldwide with low latency. By caching content at edge locations closer to users, CloudFront reduces the distance that data must travel, which results in a faster response time and an improved experience for end users.

The service optimizes the delivery of both static and dynamic content by automatically routing requests to the nearest edge location, further enhancing the efficiency of data transmission. This capability makes CloudFront an ideal solution for delivering web assets, streaming media, and large files, which benefit significantly from improved load times and reduced latency.

In contrast, the other options do not align with CloudFront's primary purpose. Data backup and archival storage solutions pertain to services like Amazon S3 Glacier. Database management and replication are handled by services such as Amazon RDS or DynamoDB. Virtual machine hosting and management relate to services like Amazon EC2. Each of these serves distinct needs within the AWS ecosystem, but they do not serve the primary function of content delivery that CloudFront specializes in.
