Discussion
Arrange the stages of a typical cloud migration in order.
1. migrate and validate in waves
2. assess the existing workloads and their dependencies
3. optimise cost and architecture after the move
4. choose a migration strategy for each workload
Answer: C
Correct answer: 2 - 4 - 1 - 3
Assessment comes first, because a strategy cannot be chosen for a workload whose dependencies are unknown. The strategy then determines what the migration of each workload involves, the migration itself runs in waves so that lessons from one inform the next, and optimisation follows the move - deliberately, since re-architecting and right-sizing are far easier once the workload is running and measurable in its new home.
