Zorluk: ZorAWS Storage Services

A financial analysis firm runs data-intensive rendering workloads on Amazon EC2 instances. The application requires extremely low-latency, temporary block-level storage to hold transient scratch data during calculations. The data does not need to persist beyond the lifecycle of the instance and can be easily regenerated if an instance fails. To achieve the highest input/output performance (IOPS) for this temporary data at the lowest cost, which storage option should the company select?

  1. A
    Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD
  2. Amazon EC2 Instance StoreCevap
  3. C
    Amazon Elastic File System (Amazon EFS)
  4. D
    Amazon S3 Standard

Cevap

Amazon EC2 Instance Store is the correct choice because it provides locally attached, temporary block-level storage optimized for ultra-low latency and high random IOPS, suited perfectly for scratch space and temporary caches at no extra charge beyond the instance host cost.
The correct answer is Amazon EC2 Instance Store. An instance store provides temporary block-level storage for your instance. This storage is located on disks that are physically attached to the host computer. It is ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data, and other temporary content, and offers very high IOPS and ultra-low latency at no additional cost.

Adım Adım Çözüm

1
Analyze the storage requirements.
The workload requires temporary block-level storage for transient scratch data.
This helps filter out non-block options like object or file storage.
2
Identify performance and cost constraints.
The solution must achieve the highest IOPS at the lowest cost and tolerate data loss upon instance termination.
This defines the selection criteria for local vs. network-attached options.
3
Compare matching AWS storage options.
Amazon EC2 Instance Store is physically attached to the host, providing superior IOPS and lower latency than network-attached EBS, and since it is included in the instance cost, it is the most cost-effective choice for non-persistent scratch data.
This points to the instance store as the optimal solution matching all criteria.
