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

A media company is planning to migrate its application portfolio to the AWS Cloud and wants to minimize implementation time and effort. Which TWO migration strategies should the company use to migrate its workloads with either zero changes to the underlying code, or only minor optimizations to use managed services without changing the core application architecture? (Select TWO.)

  1. RehostingCevap
  2. ReplatformingCevap
  3. C
    Refactoring
  4. D
    Repurchasing
  5. E
    Retaining

Cevap

The correct strategies are Rehosting and Replatforming.
The correct strategies are Rehosting and Replatforming. Rehosting, often called 'lift-and-shift', moves the application directly to the cloud without modifying its architecture or code. Replatforming, or 'lift-tinker-and-shift', introduces minor optimizations to take advantage of managed services (such as migrating a database to Amazon RDS) without altering the application's core architecture.

Adım Adım Çözüm

1
Analyze the migration requirements in the scenario.
The company wants to migrate workloads with either zero changes to code or only minor optimizations to use managed services, without altering the core application architecture.
This establishes the constraints of the migration, ruling out strategies that require code rewriting or vendor changes.
2
Evaluate the 6 Rs migration strategies against these requirements.
Rehosting ('lift-and-shift') requires no changes. Replatforming ('lift-tinker-and-shift') involves only minor optimizations (like adopting managed services) without changing the core architecture. Refactoring requires re-architecting/code changes, Repurchasing changes the application to a new product (SaaS), and Retaining leaves the application on-premises.
To select the two correct strategies that fit the criteria.

Anahtar Kavram

Cloud migration strategies (the 6 Rs), specifically Rehosting and Replatforming, which minimize changes to code and architecture during migration.
