A media company is storing large video archives on Amazon S3 Standard-IA. These archives are accessed infrequently, typically once every few months, but require immediate retrieval when requested. The company wants to reduce storage costs while maintaining high availability and rapid access. Which S3 storage class is the most cost-effective solution for this requirement?

  1. AAmazon S3 Intelligent-Tiering
  2. BAmazon S3 Glacier Flexible Retrieval
  3. CAmazon S3 Standard
  4. DAmazon S3 One Zone-IA
Show answer & explanation

Correct answer: A. Amazon S3 Intelligent-Tiering

Amazon S3 Intelligent-Tiering automatically moves data between access tiers based on access patterns, optimizing costs without performance impact. It is ideal for data with unknown or changing access patterns, providing the required immediate retrieval.

Why the other options are wrong

  • B. S3 Glacier Flexible Retrieval is designed for archival data with longer retrieval times and higher retrieval costs.
  • C. S3 Standard is more expensive for infrequently accessed data.
  • D. S3 One Zone-IA is cheaper than S3 Standard-IA but offers lower durability as data is stored in a single Availability Zone.

Amazon S3 Intelligent-Tiering

An S3 storage class that automatically optimizes storage costs by moving data between two access tiers (frequent and infrequent access) based on changing access patterns.

  • Automatically moves data to the most cost-effective access tier.
  • Ideal for data with unknown or changing access patterns.
  • No performance impact due to tiering.
