A company is setting up a new application on a single Amazon EC2 instance. The application requires a dedicated, persistent block storage volume that provides low-latency performance and is attached directly to the instance. Which AWS storage service should the company use?

  1. A
    Amazon Elastic File System (Amazon EFS)
  2. Amazon Elastic Block Store (Amazon EBS)Answer
  3. C
    Amazon Simple Storage Service (Amazon S3)
  4. D
    Amazon S3 Glacier Flexible Retrieval

Answer

Amazon Elastic Block Store (Amazon EBS)
Amazon Elastic Block Store provides high-performance, persistent block storage volumes that are designed to be attached to a single EC2 instance, matching the requirements of low latency and direct attachment.

Step-by-Step Solution

1
Identify the storage requirements from the scenario.
The scenario requires a persistent block storage volume attached to a single Amazon EC2 instance with low-latency performance.
This helps narrow down the choices by matching the storage type (block) and the attachment type (directly to a single instance).
2
Evaluate the available AWS storage services against these requirements.
Amazon Elastic Block Store provides block-level storage volumes that attach directly to an EC2 instance. Amazon Simple Storage Service provides object storage, Amazon Elastic File System provides shared file storage, and Amazon S3 Glacier is for archival storage.
Matching the features of each service reveals that only the elastic block store option meets the specific low-latency, block-level attachment requirements.
