A company wants to deploy a web application on AWS that serves audio and video content. Which AWS service would provide high availability and scalability in this situation?

Amazon S3 is an object storage service designed for high durability, availability, and scalability. It is the ideal service for storing and serving static content such as audio and video files for a web application. S3 is built to store and retrieve any amount of data from anywhere and can be integrated with Amazon CloudFront to deliver content with low latency globally. Its architecture provides inherent high availability and scales automatically to handle traffic demands, meeting all the requirements of the scenario.

A. Amazon EBS provides block-level storage volumes for use with EC2 instances. It is not designed for directly serving web content.
B. Amazon EC2 provides virtual server compute capacity. While it would run the application, it is not the storage service for the media files themselves.
C. AWS Storage Gateway is a hybrid cloud storage service for connecting on-premises environments to AWS storage, not for hosting native cloud web content.
