Question
A company recently migrated its application to AWS. The application runs on Amazon EC2 Linux instances in an Auto Scaling group across multiple Availability Zones. The application stores data in an Amazon Elastic File System (Amazon EFS) file system that uses EFS Standard-Infrequent Access storage. The application indexes the company's files, and the index is stored in an Amazon RDS database. The company needs to optimize storage costs with some application and services changes. Which solution will meet these requirements MOST cost-effectively?
Options
- ACreate an Amazon S3 bucket that uses an Intelligent-Tiering lifecycle policy. Copy all files to the
- BDeploy Amazon FSx for Windows File Server file shares. Update the application to use CIFS
- CDeploy Amazon FSx for OpenZFS file system shares. Update the application to use the new
- DCreate an Amazon S3 bucket that uses S3 Glacier Flexible Retrieval. Copy all files to the S3

Explanation
To optimize storage costs, migrating data from Amazon EFS to Amazon S3 with the Intelligent- Tiering storage class is a cost-effective solution. Amazon S3 Intelligent-Tiering: This storage class automatically moves data between frequent, infrequent, and archive access tiers based on access patterns, reducing storage costs without impacting performance. Cost Savings: By leveraging Intelligent-Tiering, the company can achieve significant cost savings, especially for data with unpredictable access patterns. Application Update: The application must be updated to interact with Amazon S3 APIs for storing and retrieving files, ensuring seamless integration with the new storage solution. This approach provides a scalable, durable, and cost-effective storage solution, aligning with the company's optimization goals.
