Zorluk: ZorAWS Database Services

A technology company plans to migrate its legacy relational database to AWS. The database administrator requires root-level access to the underlying operating system to install custom security patches and configure proprietary kernel extensions. Which AWS service or resource configuration should the company choose to meet these requirements?

  1. A
    Amazon RDS for PostgreSQL
  2. B
    Amazon DynamoDB
  3. Amazon Elastic Block Store (Amazon EBS) volume attached to an Amazon EC2 instanceCevap
  4. D
    Amazon Aurora

Cevap

Amazon Elastic Block Store (Amazon EBS) volume attached to an Amazon EC2 instance
The configuration using an Amazon Elastic Block Store (Amazon EBS) volume attached to an Amazon EC2 instance is correct. This self-managed database model gives the customer root-level control over the operating system, making it possible to install custom security updates, modify kernel extensions, and manage software dependencies directly. AWS remains responsible only for the physical infrastructure and hypervisor layers.

Adım Adım Çözüm

1
Analyze the requirements for database migration and administrative access.
The database must support relational capabilities and requires root-level access to the underlying operating system for custom security patching and kernel extensions.
This determines the level of control needed over the database environment (managed vs. self-managed).
2
Evaluate the management boundaries of AWS database services under the Shared Responsibility Model.
Fully managed relational services like Amazon RDS and Amazon Aurora do not allow customer access to the underlying operating system or servers.
Managed database services offload operating system tasks to AWS, which restricts administrative OS access.
3
Select the appropriate service or resource configuration that offers OS-level access.
Running the relational database on an Amazon EC2 instance backed by Amazon EBS block storage allows the customer to maintain full administrative control, including operating system and kernel customization.
An EC2-hosted database is self-managed, shifting OS patching and custom configuration responsibilities entirely to the customer.
