Which AWS service meets these requirements?

Explanations:

Amazon CloudFront is a Content Delivery Network (CDN) that securely delivers data, videos, applications, and APIs to users globally, ensuring low latency and high transfer speeds. It integrates with other AWS services and provides features like SSL encryption, access control, and real-time analytics.

Elastic Load Balancing (ELB) is a service that automatically distributes incoming application traffic across multiple targets, such as EC2 instances. It is not designed specifically for content delivery and does not function as a CDN.

Amazon S3 (Simple Storage Service) is an object storage service for storing and retrieving any amount of data. While it can serve content, it does not provide the CDN capabilities, such as caching and low-latency access to users globally, that are essential for a CDN.

Amazon Elastic Transcoder is a service for converting media files from one format to another. It is not a CDN and does not provide secure content delivery or caching functionalities required for global distribution of data, videos, or applications.
