Difficulty: MediumAWS Storage Services

A startup is launching a new public web portal and needs to store and distribute marketing assets, such as images, PDF brochures, and videos, directly to global website visitors. The storage solution must scale automatically to support millions of concurrent web requests, be accessible via HTTP/HTTPS, and offer durability of at least 99.999999999%99.999999999\%. Which AWS storage service should the startup select for this requirement?

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

Answer

The correct answer is Amazon Simple Storage Service (Amazon S3).
Amazon Simple Storage Service (Amazon S3) is designed as a highly durable object storage service that automatically scales to handle any volume of web requests. Because objects stored in Amazon Simple Storage Service (Amazon S3) can be accessed directly via HTTP/HTTPS endpoints, it is the ideal choice for distributing public web assets directly to global users.

Step-by-Step Solution

1
Analyze the requirements in the scenario.
The startup needs to store and distribute media assets directly to public web users via HTTP/HTTPS, requires automatic scaling for millions of concurrent requests, and needs highly durable storage.
Understanding the specific constraints allows us to eliminate storage options that cannot serve public web requests natively or do not scale automatically.
2
Evaluate the suitability of AWS storage types.
Amazon Simple Storage Service (Amazon S3) is object storage accessible via URLs, scales dynamically to handle massive web requests, and offers 99.999999999%99.999999999\% durability. Amazon Elastic Block Store (Amazon EBS) and Amazon Elastic File System (Amazon EFS) require attachment to compute instances and cannot serve HTTP/HTTPS requests directly. Amazon S3 Glacier is for archives and has retrieval delays.
Matching the characteristics of each storage type against the portal's public distribution and scaling needs leads to the correct choice.

Key Concept

AWS storage services differ in their access methods, scaling capabilities, and use cases, with Amazon Simple Storage Service (Amazon S3) being the primary service for internet-accessible object storage.
