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

EduPath Learning, an online education provider, is migrating its systems to the AWS Cloud. The migration team has decided on the following actions:

1. The relational database for the student portal will be moved to Amazon RDS for PostgreSQL to take advantage of automated patching and backups, without changing the application logic.
2. A legacy system used for processing legacy course credits, which is planned for decommissioning next year, will be kept on-premises in its current state for now.

Which two of the following migration strategies are represented by these decisions?

  1. A
    Rehosting
  2. ReplatformingCevap
  3. C
    Refactoring
  4. RetainingCevap
  5. E
    Repurchasing

Cevap

Replatforming and Retaining
Replatforming represents the decision to move the database to Amazon RDS to benefit from managed services without modifying the core application code. Retaining represents the decision to keep the legacy billing system on-premises in its current state until it is decommissioned.

Adım Adım Çözüm

1
Analyze the first decision: migrating the database to Amazon RDS for PostgreSQL without changing application logic to leverage managed backups.
This is Replatforming (lift-tinker-and-shift) because the database is optimized for cloud management without code changes.
Identifying the characteristics of migrating to a managed service like RDS matches the Replatforming strategy.
2
Analyze the second decision: keeping the legacy course-credits system on-premises in its current state because it is scheduled to be retired.
This is Retaining because the workload is kept on-premises as-is during the migration process.
Identifying that keeping a workload on-premises during migration fits the Retaining strategy.
