Zorluk: OrtaAWS Storage Services

A logistics company is deploying a fleet of delivery tracking applications on Amazon EC2. The applications require two types of storage:

1. A high-performance block storage volume attached to a single EC2 instance that holds transaction logs and must persist if the instance is stopped or restarted.
2. A fully managed shared file system that can be accessed concurrently by multiple EC2 instances across multiple Availability Zones to store shared configuration and report templates.

Which TWO AWS storage services should the company select to meet these requirements?

  1. Amazon EBSCevap
  2. Amazon EFSCevap
  3. C
    Amazon EC2 Instance Store
  4. D
    Amazon S3
  5. E
    AWS Storage Gateway

Cevap

Amazon EBS and Amazon EFS
Amazon EBS is the correct choice for persistent block storage for an EC2 instance, ensuring logs are preserved during instance stops. Amazon EFS is correct for a shared file system that must be accessed concurrently by multiple EC2 instances across multiple Availability Zones.

Adım Adım Çözüm

1
Analyze the first requirement: persistent block storage for transaction logs attached to a single EC2 instance.
Identify Amazon EBS as the service that provides persistent, low-latency block storage volumes for EC2.
Since the data must persist when the instance is stopped or restarted, ephemeral options like Instance Store are unsuitable.
2
Analyze the second requirement: a shared file system accessible by multiple EC2 instances across multiple Availability Zones simultaneously.
Identify Amazon EFS as the service that provides a serverless, shared file system supporting the Network File System (NFS) protocol.
EFS allows concurrent access from multiple instances across different Availability Zones, unlike standard block storage.
