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?
- AAmazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD
- Amazon EC2 Instance StoreAnswer
- CAmazon Elastic File System (Amazon EFS)
- DAmazon S3 Standard
Answer
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.
