Question

Difficulty: MediumAWS Storage Services

An online video education platform runs its transcoding application on Amazon EC2 instances. The platform has two key storage requirements:

1. High-throughput, low-latency temporary storage to buffer video chunks during the active transcoding process, where data persistence is not required.
2. Highly durable, cost-effective object storage to store and distribute the final transcoded video files to global users with immediate access.

Which two AWS storage services or features should the platform select to meet these requirements?

  1. Amazon S3 StandardAnswer
  2. Amazon EC2 Instance StoreAnswer
  3. C
    Amazon EBS Cold HDD (sc1)
  4. D
    Amazon S3 Glacier Deep Archive
  5. E
    Amazon Elastic File System (Amazon EFS)

Answer

Amazon S3 Standard and Amazon EC2 Instance Store
Amazon S3 Standard is chosen because it is a highly durable, scalable object storage service that provides immediate retrieval for global users. Amazon EC2 Instance Store is chosen because it provides high-throughput, low-latency block storage that is physically attached to the host, which is ideal for temporary scratch space and buffering where data persistence is not needed.

Step-by-Step Solution

1
Analyze the requirement for temporary transcoding buffer storage that needs high throughput, low latency, and does not require persistence.
Identify Amazon EC2 Instance Store as the local, temporary block storage that provides the necessary performance.
Instance store is physically attached to the host, providing very high performance for temporary files without the persistence overhead of EBS.
2
Analyze the requirement for storing and distributing final video files as durable objects with immediate retrieval.
Identify Amazon S3 Standard as the object storage tier that offers high durability and immediate access.
S3 Standard is designed for active data distribution and meets the immediate access and durability criteria.
