Question

Difficulty: MediumAWS Storage Services

A media company uploads news broadcast videos daily to Amazon S3. These video files are heavily accessed by viewers for the first 14 days after upload. After this initial period, the videos are rarely requested. However, if a video is requested, it must be available immediately (within milliseconds) for streaming. The company wants a cost-effective storage class that maintains high availability and durability across multiple Availability Zones. Which Amazon S3 storage class is the most appropriate for storing the videos after the first 14 days?

  1. A
    Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA)
  2. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)Answer
  3. C
    Amazon S3 Glacier Flexible Retrieval
  4. D
    Amazon S3 Glacier Deep Archive

Answer

Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is the correct storage class because it provides cost-effective storage for infrequently accessed data with millisecond retrieval times and multi-AZ redundancy.
The correct storage class is Amazon S3 Standard-Infrequent Access (S3 Standard-IA). It is optimized for data that is accessed less frequently but requires immediate (millisecond) access when requested. It also stores data redundantly across multiple Availability Zones, meeting all of the company's requirements.

Step-by-Step Solution

1
Identify the key access pattern requirements from the scenario.
The data is accessed frequently for the first 14 days, and then rarely accessed. However, when accessed, retrieval must be immediate (in milliseconds).
Understanding the retrieval latency requirement helps eliminate archival storage classes that have retrieval delays.
2
Identify the availability and durability requirements.
The storage must maintain high availability and durability across multiple Availability Zones.
This helps distinguish between multi-AZ storage classes and single-AZ storage classes.
3
Evaluate the matching Amazon S3 storage classes against the requirements.
Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is the only class that offers lower storage costs for infrequently accessed data, millisecond access, and multi-AZ resilience.
Matching the characteristics of each storage class to the business requirements yields the correct solution.
