Zorluk: KolayHigh-Performing and Scalable Storage Solutions

A company is deploying a media rendering application on a fleet of Amazon EC2 Linux instances. The instances must concurrently access a shared file system to read raw media files and write rendered outputs. The workload is highly unpredictable, with rapid spikes in throughput requirements.

Which storage solutions will meet these requirements while providing the necessary shared access? (Select TWO.)

  1. Amazon Elastic File System (Amazon EFS) configured with Elastic ThroughputCevap
  2. Amazon FSx for LustreCevap
  3. C
    Amazon EBS gp3 volumes configured with Amazon EBS Multi-Attach
  4. D
    Amazon EBS io2 volumes formatted with an EXT4 file system and attached to multiple instances
  5. E
    Amazon S3 Glacier Flexible Retrieval with S3 Select

Cevap

Amazon Elastic File System (Amazon EFS) configured with Elastic Throughput and Amazon FSx for Lustre
Amazon Elastic File System (Amazon EFS) with Elastic Throughput and Amazon FSx for Lustre both support concurrent POSIX-compliant read and write access across multiple Linux instances. Amazon EFS with Elastic Throughput dynamically scales throughput to handle unpredictable spikes. Amazon FSx for Lustre is specifically optimized for high-performance workloads like media rendering, providing sub-millisecond latencies and high throughput.

Adım Adım Çözüm

1
Identify the shared access and performance requirements of the workload.
The workload requires concurrent read/write access from multiple EC2 Linux instances with sub-millisecond latency and the ability to scale throughput for unpredictable spikes.
This establishes that the solution must be a shared file system rather than standard block storage, and it must support auto-scaling throughput.
2
Evaluate the AWS shared file storage options.
Amazon EFS and Amazon FSx for Lustre are native shared file systems that support concurrent access from Linux instances. EFS with Elastic Throughput handles unpredictable spikes, while FSx for Lustre is designed for high-performance workloads like media rendering.
This identifies the correct services that meet all specified requirements.
3
Analyze why EBS Multi-Attach and S3 Glacier options are incorrect.
EBS gp3 does not support Multi-Attach. EBS io2 with a standard EXT4 file system will lead to data corruption as it is not a clustered file system. S3 Glacier is for cold archiving and cannot provide the necessary performance or file interface.
This eliminates the incorrect storage configurations.
