Question 22 of 100 | ← Chapter 11

Q722. A company has several on-premises Internet Small Computer Systems Interface (ISCSI) network storage servers. The company wants to reduce the number of these servers by moving to the AWS Cloud. A solutions architect must provide low-latency access to frequently used data and reduce the dependency on on-premises servers with a minimal number of infrastructure changes.Which solution will meet these requirements?

Correct Answer: D. Deploy an AWS Storage Gateway volume gateway that is configured with cached volumes.

Explanation

To meet the requirements of providing low-latency access to frequently used data, reducing the dependency on on-premises servers with minimal infrastructure changes, and moving to the AWS Cloud, the most suitable solution is:D. Deploy an AWS Storage Gateway volume gateway that is configured with cached volumes.Option D, deploying an AWS Storage Gateway volume gateway with cached volumes, aligns with the requirements by providing low-latency access to frequently used data and minimizing the infrastructure changes:- AWS Storage Gateway: AWS Storage Gateway enables on-premises applications to seamlessly integrate with AWS storage services. It provides a hybrid cloud storage solution.- Volume gateway: With volume gateway, the on-premises applications access AWS storage volumes as iSCSI devices. It allows you to store data in Amazon S3 and retain frequently accessed data in a local cache for low-latency access.- Cached volumes: Cached volumes in AWS Storage Gateway keep the frequently used data locally in the on-premises cache while asynchronously backing up the data to Amazon S3. This minimizes the latency for frequently accessed data and reduces the dependency on on-premises servers.Option A, deploying an Amazon S3 File Gateway, is not the optimal choice as it is designed for file-level access to S3 and may not provide the low-latency access required.Option B, deploying Amazon Elastic Block Store (Amazon EBS) storage with backups to Amazon S3, does not minimize the infrastructure changes as it involves migrating and managing block-level storage volumes in EBS. It also does not provide low-latency access to frequently used data.Option C, deploying an AWS Storage Gateway volume gateway with stored volumes, is not the best choice as it does not provide low-latency access to frequently used data. In this configuration, all data is stored on-premises, and backups are taken in Amazon S3.Therefore, the solution that meets the requirements of low-latency access to frequently used data, reducing dependency on on-premises servers with minimal infrastructure changes is D: Deploy an AWS Storage Gateway volume gateway that is configured with cached volumes. This solution allows for seamless integration with AWS storage services, provides low-latency access to frequently used data, and minimizes the need for on-premises servers by leveraging the cloud storage capabilities of AWS.
