Difficulty: MediumAWS Storage Services

A media company is setting up a video processing pipeline on AWS and requires two types of storage:

First, a cost-effective storage class to archive finished projects for compliance. The archives will be rarely accessed, and a retrieval time of up to 12 hours is acceptable.

Second, a temporary scratch space for active video rendering on a single Amazon EC2 instance. This space must deliver the lowest possible latency and highest random I/O performance, but the data does not need to persist when the instance is stopped or terminated.

Which two AWS storage options should the company select to meet these requirements? (Select TWO.)

  1. Amazon S3 Glacier Deep ArchiveAnswer
  2. Amazon EC2 Instance StoreAnswer
  3. C
    Amazon Elastic File System (Amazon EFS)
  4. D
    Amazon Elastic Block Store (Amazon EBS)
  5. E
    Amazon S3 Standard-Infrequent Access (S3 Standard-IA)

Answer

Amazon S3 Glacier Deep Archive and Amazon EC2 Instance Store
Amazon S3 Glacier Deep Archive is the most cost-effective solution for archival storage where a 12-hour retrieval time is acceptable. Amazon EC2 Instance Store is ideal for temporary scratch storage because it is physically attached to the host computer, offering low-latency, high-speed random I/O at no additional cost, while automatically deleting the data when the instance stops or terminates.

Step-by-Step Solution

1
Identify the storage requirements for archiving footage.
The footage is rarely accessed, requires the lowest cost, and can tolerate a 12-hour retrieval window, matching the characteristics of Amazon S3 Glacier Deep Archive.
This maps the business constraints to the most economical long-term archival tier.
2
Identify the storage requirements for active video rendering.
The rendering requires temporary scratch space on a single EC2 instance with high performance, ultra-low latency, and no persistence after the instance stops, matching the characteristics of Amazon EC2 Instance Store.
This maps the performance and durability requirements to the correct block storage type.

Key Concept

Selecting the correct AWS storage services based on access frequency, performance, durability, and cost requirements.
