Difficulty: EasyUnderstand the benefits of and strategies for migration to the AWS Cloud

A manufacturing firm, AeroParts, is preparing to migrate its IT portfolio to the AWS Cloud. The migration team has identified two workloads:

1. An on-premises web application database that they want to move to Amazon RDS to reduce database administration overhead, without changing the core application logic.
2. Several old testing servers that are no longer actively used by any department.

Which TWO migration strategies should the company use for these workloads?

  1. A
    Rehosting
  2. ReplatformingAnswer
  3. C
    Refactoring
  4. D
    Repurchasing
  5. RetiringAnswer

Answer

The correct strategies are Replatforming and Retiring.
Replatforming is the strategy of moving workloads to the cloud while making minor optimizations (like shifting to Amazon RDS to reduce database administration) without changing the core application logic. Retiring is the strategy of turning off or decommissioning IT systems that are no longer needed, such as the unused testing servers.

Step-by-Step Solution

1
Analyze the first workload, which involves moving a database to Amazon RDS (a managed service) without making changes to the application's core logic.
Identify that adopting a managed database service without changing application architecture corresponds to Replatforming.
Replatforming allows organizations to gain cloud benefits like managed services without a full rewrite.
2
Analyze the second workload, which consists of legacy testing servers that are no longer actively used.
Identify that decommissioning unused assets corresponds to Retiring.
Retiring helps organizations reduce costs by shutting down servers that are no longer needed.
