Question
A research group wants to use EC2 instances to run a scientific computation application that has a fault tolerant architecture. The application needs high-performance hardware disks that provide fast I/O performance. As a Cloud Practitioner, which of the following storage options would you recommend as the MOST cost-effective solution?Question 24Answera.Amazon EBSb.Amazon EFSc.Amazon S3d.Instance Store
Solution
The most cost-effective solution for a high-performance hardware disk that provides fast I/O performance would be d. Instance Store.
Here's why:
a. Amazon EBS: EBS is a block storage service for use with Amazon EC2. EBS is suitable for EC2 instances by providing highly available and reliable storage volumes, but it's not the most cost-effective for high I/O performance.
b. Amazon EFS: EFS is a file storage service for use with AWS Cloud services and on-premises resources. It's easy to use and offers a simple interface, but it's more expensive than instance store and not optimized for high I/O performance.
c. Amazon S3: S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. However, it's not suitable for high I/O operations as it's designed for storing and retrieving any amount of data from anywhere.
d. Instance Store: Instance store provides temporary block-level storage for instances. This storage is located on disks that are physically attached to the host computer. Instance store is ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data, and other temporary content, or for data
