Difficulty: MediumAWS Storage Services

A healthcare organization needs to store patient medical records for 10 years to meet regulatory compliance requirements. The records are rarely accessed after the initial treatment period, but the organization must be able to retrieve them within 3 to 5 hours if an audit occurs. The solution must minimize storage costs. Which Amazon S3 storage class is the most cost-effective choice for this scenario?

  1. A
    Amazon S3 Standard-Infrequent Access (S3 Standard-IA)
  2. B
    Amazon S3 Glacier Deep Archive
  3. Amazon S3 Glacier Flexible RetrievalAnswer
  4. D
    Amazon EBS Provisioned IOPS SSD

Answer

Amazon S3 Glacier Flexible Retrieval
Amazon S3 Glacier Flexible Retrieval is the most cost-effective option because it is specifically designed for archive data that does not require immediate retrieval but requires access options ranging from minutes to hours. The standard retrieval option fits the 3-to-5-hour requirement perfectly while keeping storage costs extremely low.

Step-by-Step Solution

1
Analyze the access pattern and retrieval requirements.
The medical records are rarely accessed (archival use case) but must be retrievable within a 3-to-5-hour window.
This helps filter out storage classes that do not meet the retrieval timeframe or are optimized for active datasets.
2
Evaluate the cost and retrieval times of candidate Amazon S3 storage classes.
Amazon S3 Glacier Flexible Retrieval offers standard retrieval in 3 to 5 hours at a very low storage cost. Amazon S3 Glacier Deep Archive takes 12 hours (too slow). Amazon S3 Standard-IA is for millisecond access and is more expensive.
Choosing the service that meets the SLA while minimizing storage cost ensures the most optimal architecture.
