Question 91 of 100 | ← Chapter 14

Q1091. A company wants to migrate an application that processes logs to AWS. Currently, the application runs on an on-premises storage area network (SAN).The application reads and processes large log files sequentially. The application requires throughput of up to 500 MBps.A solutions architect needs to migrate the application with minimal change to the application architecture.Which solution will meet these requirements in the MOST cost-effective way?

Correct Answer: B. Use a Throughput Optimized HDD (st1) Amazon Elastic Block Store (Amazon EBS) volume with provisioned storage based on the throughput requirement.

Explanation

To determine the most cost-effective solution for migrating an application that processes logs to AWS, with minimal change to the application architecture and a requirement for throughput of up to 500 MBps, let's evaluate each option:A. Use a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume with 500 MBps provisioned throughput.Cost: Generally higher due to the SSD nature and provisioned throughput. Performance: Excellent for a mix of sequential and random workloads. Suitability: While suitable, may not be the most cost-effective for purely sequential workloads. B. Use a Throughput Optimized HDD (st1) Amazon Elastic Block Store (Amazon EBS) volume with provisioned storage based on the throughput requirement.Cost: Lower than SSD options due to the use of HDD.Performance: Optimized for sequential workloads with high throughput. Suitability: Highly suitable for the application's requirements of reading and processing large log files sequentially.C. Use a Cold HDD (sc1) Amazon Elastic Block Store (Amazon EBS) volume with provisioned storage based on the throughput requirement.Cost: Lower than SSD options, but may not be as cost-effective as st1 for high throughput needs. Performance: Designed for infrequently accessed data with lower costs. Suitability: Less suitable for applications requiring high throughput due to its focus on cost savings for infrequently accessed data.D. Use a Provisioned IOPS (io1) Amazon Elastic Block Store (Amazon EBS) volume with 500 MBps Provisioned throughput.Cost: Highest among the options due to the focus on IOPS and provisioned throughput. Performance: Excellent for workloads requiring consistent and predictable I/O performance. Suitability: While capable, overly expensive for an application primarily requiring sequential throughput. Given the application's requirement for sequential processing of large log files with a throughput of up to 500 MBps, and the need for a cost-effective solution with minimal change to the application architecture, the best option is:B. Use a Throughput Optimized HDD (st1) Amazon Elastic Block Store (Amazon EBS) volume with provisioned storage based on the throughput requirement.This solution provides the necessary throughput at a lower cost compared to SSD options, making it the most cost-effective choice for the given application requirements.
