Cloud Conceptsmedium

During a migration portfolio assessment, a company sorts its applications by migration strategy. Which applications are the best candidates for the retain strategy, keeping them in the source environment for now? (Choose TWO.)

Select 2 answers.

Show answer and explanation

Answers:

A. An application whose servers and software were upgraded last quarter
D. A plant-floor application that depends on specialized hardware with no cloud equivalent

Retain is the strategy for applications that you want to keep in the source environment, or that you are not ready to migrate yet. Among the common use cases AWS lists are applications that were recently upgraded, where migration is postponed until the next technical refresh to protect that investment, and unresolved physical dependencies, such as reliance on specialized hardware like machines in a manufacturing plant.

Option B describes retire: an application with no business value and no inbound connections in 90 days should be decommissioned, not kept. Option C describes repurchase: replacing a custom application with a SaaS product that already exists. (Retain applies only while you *wait* for a SaaS version to be released.) Option E describes rehost: moving the application to AWS without changes is a migration, not keeping it where it is.
