Zorluk: OrtaUnderstand the benefits of and strategies for migration to the AWS Cloud

An agricultural technology firm, GreenGrow Solutions, is migrating its legacy inventory tracking system to the AWS Cloud. The system consists of a web server and a self-managed PostgreSQL database currently running on-premises. To minimize application code modifications, the team decides to migrate the web server to Amazon EC2 without changes. However, they decide to move the database to Amazon Relational Database Service (Amazon RDS) for PostgreSQL to eliminate database administration tasks like patching and backups. Which migration strategy is GreenGrow Solutions applying to the database tier?

  1. A
    Rehosting
  2. ReplatformingCevap
  3. C
    Refactoring
  4. D
    Retaining

Cevap

Replatforming
The correct answer is Replatforming. GreenGrow Solutions is optimization-tuning their database by moving it from a self-managed virtual machine to a fully managed service (Amazon RDS) to reduce administrative overhead (like patching and backups) without changing the core application code or database engine type.

Adım Adım Çözüm

1
Analyze the database migration requirements from the scenario.
The web server is migrated without changes, but the database is moved to Amazon RDS to reduce administrative overhead.
To identify how each tier of the application is handled during the migration.
2
Compare the database migration details against the 6 Rs migration strategies.
Migrating a self-managed database to a fully managed database service (Amazon RDS) without changing the database type represents Replatforming.
To align the migration actions with the correct cloud migration terminology.
3
Evaluate the distractors based on definitions and cloud economics.
Rehosting is direct lift-and-shift; Refactoring requires code rewrites; Retaining keeps the database on-premises and does not convert OpEx to CapEx.
To eliminate the incorrect options and confirm the single correct answer.
