AWS Certified Cloud Practitioner (CLF-C02)Cloud ConceptsHard
A company runs its entire data center on VMware virtualization technology. It wants to move workloads to AWS with the least possible changes to its existing VMware tools, processes, and architecture, without purchasing new physical hardware or re-hosting onto native EC2 instances. Which migration strategy best fits this requirement?
- ARehost
- BRefactor
- CReplatform
- DRelocate
Show answer & explanationAnswer & explanation
Correct answer: D. Relocate
Relocate involves moving infrastructure to the cloud at the hypervisor level, such as using VMware Cloud on AWS, without changing the underlying architecture, purchasing new hardware, or modifying operations, which distinguishes it from Rehost.
Why the other options are wrong
- A. Rehost typically involves migrating to native EC2 instances, which changes the underlying virtualization platform.
- B. Refactor involves significant architectural redesign, which contradicts the requirement for minimal change.
- C. Replatform involves making some optimizations during the move, not just relocating the hypervisor.
Relocate (7 Rs)
A migration strategy that moves infrastructure to the cloud at the hypervisor level (e.g., VMware Cloud on AWS) without changing the underlying architecture or purchasing new hardware.
- Distinct from Rehost because no new EC2 instances are provisioned
- Preserves existing VMware tools and skills
- Fastest option for large-scale VMware environments
Memory trick: Relocate = 'Relocate the whole virtualization layer, unchanged.'
