01What is cloud landing zone, and why is it important for a Cloud Platform Architect?
A clear 90-second answer
Say this first: cloud landing zone should be explained through its purpose, the boundary where it applies, and the evidence that shows it is working.
Use a real scenario
Imagine a service being expanded from one product team to several dependent teams. The team must decide how to apply cloud landing zone, verify the result, and explain the user impact. For a Cloud Platform Architect, attach the explanation to an architecture decision record and NFR matrix.
Show judgment
- name the concept, give one concrete use, and say how you would check the result.
- State the constraint that could change your decision, such as scale, data sensitivity, recovery target, or team ownership.
- Call out coupling, unclear ownership, or an irreversible vendor choice and the control that reduces it.
Concrete check
