Question

Difficulty: MediumAWS Storage Services

A medical clinic needs to store patient records that are older than one year. The clinic rarely accesses these records, but when they do, the files must be retrieved immediately in milliseconds. The clinic wants to minimize storage costs while maintaining high durability. Which AWS storage class is the most appropriate for this workload?

  1. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)Answer
  2. B
    Amazon S3 Glacier Flexible Retrieval
  3. C
    Amazon S3 Standard
  4. D
    Amazon Elastic Block Store (Amazon EBS)

Answer

Amazon S3 Standard-Infrequent Access (S3 Standard-IA)
Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is the optimal choice because it is specifically designed for data that is accessed less frequently but requires rapid (millisecond) access when requested. It provides the same durability as S3 Standard but at a lower storage price point, matching all constraints in the scenario.

Step-by-Step Solution

1
Analyze the access pattern and retrieval requirements.
The data is rarely accessed (infrequent access) but must be available in milliseconds (immediate retrieval).
This rules out archival classes like Glacier that require minutes or hours to retrieve data.
2
Compare cost-effective storage options that support immediate retrieval.
Amazon S3 Standard-Infrequent Access (S3 Standard-IA) offers lower storage pricing than S3 Standard while meeting the millisecond retrieval requirement.
This satisfies the clinic's requirement to minimize storage costs while retaining high durability and low-latency access.

Key Concept

Selecting cost-effective S3 storage classes based on access frequency and retrieval time constraints.
