Question

A leading e-commerce company needs a storage solution for 1000 Linux servers, accessible in multiple availability zones, with rapidly changing data and high performance. The servers use a hierarchical directory structure via the NFSv4 protocol. As the Solutions Architect, which service is the most cost-effective choice for meeting these requirements?

a) Amazon EBS (Elastic Block Store).
b) Amazon S3 (Simple Storage Service).
c) Amazon Glacier.
d) Amazon EFS (Elastic File System).

Answer 1

D) Amazon EFS (Elastic File System) is the most cost-effective storage solution for 1000 Linux servers needing high performance and NFSv4 support across multiple availability zones.

Step-by-step explanation:

The most cost-effective choice for a storage solution that caters to 1000 Linux servers, accessible across multiple availability zones, with rapidly changing data and high performance requirements, and uses the NFSv4 protocol with a hierarchical directory structure is Amazon EFS (Elastic File System).

Unlike Amazon EBS (Elastic Block Store), which is designed for single instance storage and does not natively support being mounted across multiple availability zones, Amazon EFS is designed to be highly available and scalable, and supports being shared across many instances, making it suitable for the outlined scenario.

While Amazon S3 (Simple Storage Service) is great for object storage and is highly durable, it does not provide a file system interface or a hierarchical storage system as required in this case. Amazon Glacier is designed for long-term archival storage and is not appropriate for scenarios requiring rapid access and high performance.
