Zorluk: OrtaHigh-Performing and Scalable Storage Solutions

A company is deploying a media processing application on a fleet of Amazon EC2 instances distributed across 33 Availability Zones. The application requires concurrent, shared access to a POSIX-compliant file system to read and write large media files. The storage solution must scale throughput dynamically to handle unpredictable spikes in file processing demands while maintaining low latency. Which storage configuration should a solutions architect recommend to meet these requirements?

  1. A
    Amazon EBS gp3 volumes with Multi-Attach enabled
  2. Amazon EFS using Elastic throughput modeCevap
  3. C
    Amazon EBS io2 volumes with Multi-Attach enabled
  4. D
    Amazon S3 bucket mounted on the EC2 instances using the Amazon S3 Mountpoint utility

Cevap

Amazon EFS using Elastic throughput mode
The correct option is the one specifying Amazon EFS using Elastic throughput mode. Amazon EFS provides a fully managed, POSIX-compliant shared file system that allows concurrent read and write access from EC2 instances across multiple Availability Zones. By using Elastic throughput mode, EFS dynamically adjusts throughput capacity in response to workload activity, which perfectly matches the unpredictable spike requirements.

Adım Adım Çözüm

1
Analyze the requirement for shared POSIX-compliant file access across multiple Availability Zones.
Identify that Amazon EBS volumes (including gp3 and io2) cannot be shared across multiple Availability Zones, as EBS Multi-Attach is restricted to a single Availability Zone. Amazon S3 is not POSIX-compliant.
This narrows the candidate services down to Amazon EFS or Amazon FSx, which support multi-AZ shared access.
2
Evaluate the throughput requirements of the media processing workload.
The application requires scaling throughput dynamically to handle unpredictable spikes.
Amazon EFS with Elastic throughput mode automatically scales throughput to meet the workload demand without manual provisioning, optimizing performance and cost.
