A company is building a web-based application running on Amazon EC2 instances in multiple Availability Zones.The web application will provide access to a repository of text documents totaling about 900 TB in size.The company anticipates that the web application will experience periods of high demand.A solutions architect must ensure that the storage component for the text documents can scale to meet the demand of the application at all times.The company is concerned about the overall cost of the solution.

Which storage solution meets these requirements MOST cost-effectively?

Amazon Elastic Block Store (Amazon EBS)

Amazon Elastic File System (Amazon EFS)

Amazon OpenSearch Service (Amazon Elasticsearch Service)

Amazon S3

Explanations:

Amazon EBS is designed for block storage and is typically used for individual instances. It is not the most cost-effective solution for large datasets.

Amazon EFS provides scalable file storage, but it can be more expensive than other options, especially for large amounts of data like 900 TB.

Amazon OpenSearch Service is mainly for search and analytics and is not suitable for storing large amounts of text documents cost-effectively.

Amazon S3 is an object storage service that is highly scalable, cost-effective for storing large volumes of data, and suitable for web-based applications.
