A company needs to store its files in the AWS Cloud. Users must be able to download the files directly by using a public URL. Which AWS service provides this functionality?

Amazon Redshift is a data warehousing service, designed for analytics on large datasets, not for general-purpose file storage with public download links.

Amazon Elastic Block Store (Amazon EBS) provides block-level storage volumes for use with Amazon EC2 instances and is not designed for direct public file access via URLs.

Amazon Elastic File System (Amazon EFS) provides scalable file storage for Amazon EC2 instances and on-premises servers, primarily for shared file access within an environment, not for direct public URL downloads.

Amazon S3 (Simple Storage Service) is an object storage service that offers high scalability, data availability, security, and performance, making it ideal for storing various types of files. Objects stored in S3 can be easily configured for public read access through bucket policies or object ACLs, allowing users to download files directly via a unique public URL.
