Zorluk: OrtaAWS Storage Services

A technology company is building a containerized web application on AWS that runs across multiple Availability Zones. The application architecture has two key storage requirements:

First, it requires a fully managed, shared file system that can be concurrently mounted by all container instances to access shared configuration files.

Second, it requires a cost-effective object storage solution to store user profile images that are accessed infrequently but must be available immediately when requested.

Which two AWS storage services should the company select to meet these requirements? (Select TWO.)

  1. Amazon Elastic File System (Amazon EFS)Cevap
  2. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)Cevap
  3. C
    Amazon Elastic Block Store (Amazon EBS)
  4. D
    Amazon S3 Glacier Flexible Retrieval
  5. E
    Amazon EC2 Instance Store

Cevap

Amazon Elastic File System (Amazon EFS) and Amazon S3 Standard-Infrequent Access (S3 Standard-IA)
The correct options are Amazon Elastic File System (Amazon EFS) and Amazon S3 Standard-Infrequent Access (S3 Standard-IA). Amazon EFS provides a fully managed shared file system that can be accessed concurrently by multiple containers across Availability Zones, satisfying the first requirement. Amazon S3 Standard-IA offers lower-cost object storage for infrequently accessed files while still guaranteeing immediate (millisecond) retrieval times, satisfying the second requirement.

Adım Adım Çözüm

1
Analyze the first requirement: a shared file system concurrently mounted by containers across multiple Availability Zones.
Identify Amazon Elastic File System (Amazon EFS) as the appropriate service, since it supports POSIX compliance and simultaneous access from multiple instances/containers across AZs.
Amazon EBS is block storage meant for single instances (with limited Multi-Attach support not suited for general cross-AZ file systems), and Instance Store is local, temporary storage.
2
Analyze the second requirement: object storage for infrequently accessed data that must be immediately available.
Identify Amazon S3 Standard-Infrequent Access (S3 Standard-IA) as the correct choice, as it provides cheaper storage for infrequent access with millisecond retrieval.
Amazon S3 Glacier Flexible Retrieval is archival and requires minutes to hours for data retrieval, which fails the immediate availability requirement.

Anahtar Kavram

Selecting the appropriate AWS storage services (Amazon EFS for shared file storage and Amazon S3 Standard-IA for cost-effective, infrequently accessed object storage with immediate retrieval) based on application requirements.
