Zorluk: OrtaAWS Storage Services

A media company is migrating its video editing workflow to AWS. The architecture requires a storage solution that allows multiple Amazon EC2 instances to concurrently read and write to the same shared directory of raw video files. Additionally, the company needs a durable, cost-effective storage tier to store finalized video files, which must automatically transition to lower-cost archival tiers after 30 days. Which two AWS storage solutions or features should the company select to meet these requirements? (Select TWO.)

  1. Amazon Elastic File System (Amazon EFS) to serve as the shared, concurrent file system for the video editing EC2 instances.Cevap
  2. Amazon Simple Storage Service (Amazon S3) with lifecycle configurations to store finalized assets and automate archival transitions.Cevap
  3. C
    Amazon Elastic Block Store (Amazon EBS) Multi-Attach volumes to share the raw video files concurrently across instances in different Availability Zones.
  4. D
    Amazon EC2 Instance Store to store the finalized video files to ensure long-term data durability and archival compliance.
  5. E
    AWS Backup to dynamically scale the storage capacity of the video editing instances as the size of the raw video files increases.

Cevap

Amazon Elastic File System (Amazon EFS) to serve as the shared file system, and Amazon Simple Storage Service (Amazon S3) with lifecycle configurations to manage finalized assets and archival transitions.
Amazon Elastic File System (Amazon EFS) satisfies the requirement for a shared file system that multiple EC2 instances can read and write to concurrently. Amazon Simple Storage Service (Amazon S3) combined with S3 Lifecycle rules satisfies the requirement for durable, cost-effective storage that can automatically archive files to colder tiers after 30 days.

Adım Adım Çözüm

1
Analyze the requirement for concurrent, shared access to a single directory from multiple EC2 instances.
Select Amazon Elastic File System (Amazon EFS) because it is designed to be mounted simultaneously by multiple instances using the NFS protocol.
Block storage options like EBS do not easily support concurrent multi-instance writing across multiple Availability Zones without complex setup, whereas EFS handles this natively.
2
Analyze the requirement for durable, cost-effective object storage with automated transition to archival tiers after 30 days.
Select Amazon Simple Storage Service (Amazon S3) with lifecycle policies.
Amazon S3 provides high durability for finalized files, and S3 Lifecycle configurations can be set to automatically transition files to colder storage classes (such as S3 Glacier) after a set duration.

Anahtar Kavram

Selecting appropriate AWS storage services based on access pattern (shared file vs. object storage) and lifecycle management requirements.
