A company runs an application on a group of Amazon Linux EC2 instances.For compliance reasons, the company must retain all application log files for 7 years.The log files will be analyzed by a reporting tool that must be able to access all the files concurrently.

Which storage solution meets these requirements MOST cost-effectively?

Amazon Elastic Block Store (Amazon EBS)

Amazon Elastic File System (Amazon EFS)

Amazon EC2 instance store

Amazon S3

Explanations:

Amazon EBS is primarily designed for block storage and is not suitable for retaining large amounts of log data over long periods due to higher costs and limitations on concurrent access.

Amazon EFS provides scalable file storage and supports concurrent access, but it may not be the most cost-effective solution for retaining large volumes of data over 7 years compared to S3.

Amazon EC2 instance store provides temporary storage and does not persist data after the instance is terminated, making it unsuitable for long-term log retention.

Amazon S3 offers highly durable and cost-effective storage for large amounts of data, supports long-term retention, and allows concurrent access for analysis, making it the best choice for complian
