Zorluk: KolayAWS Storage Services

A company is designing an application architecture on AWS and needs to select storage solutions for two different use cases. First, they need low-latency, temporary block storage to hold temporary scratch files and cache data that can be safely discarded when the EC2 instances are stopped. Second, they need a low-cost storage solution to archive historical records that are rarely accessed but must be retrievable within a few hours. Which TWO AWS storage options should the company select to meet these requirements?

  1. Amazon EC2 Instance StoreCevap
  2. Amazon S3 Glacier Flexible RetrievalCevap
  3. C
    Amazon EBS Provisioned IOPS SSD
  4. D
    Amazon Elastic File System (Amazon EFS)
  5. E
    Amazon EBS General Purpose SSD

Cevap

The correct options are Amazon EC2 Instance Store and Amazon S3 Glacier Flexible Retrieval.
Amazon EC2 Instance Store is correct because it provides temporary, high-speed block storage directly attached to the host computer, which is ideal for temporary scratch files or buffer data that does not need to survive instance stops. Amazon S3 Glacier Flexible Retrieval is correct because it is designed for low-cost archiving of historical data that is rarely accessed, offering retrieval options that take between a few minutes and a few hours.

Adım Adım Çözüm

1
Analyze the first requirement: low-latency, temporary block storage for files that do not need to persist when the EC2 instance stops.
Amazon EC2 Instance Store fits this scenario, as it is physically attached to the host computer and is ephemeral (data is lost when the instance is stopped or terminated).
Instance Store is optimized for temporary block storage and has no ongoing cost if the instance is running, unlike persistent block storage options.
2
Analyze the second requirement: low-cost archival storage for rarely accessed records retrievable within a few hours.
Amazon S3 Glacier Flexible Retrieval fits this scenario, as it is designed for low-cost archiving with retrieval options ranging from minutes to hours.
S3 Glacier provides highly durable and extremely cheap storage for inactive data compared to active storage classes or block storage.
