Architecture and analysts: how to live with it?

How does the architecture hold sway over an analyst's work? Is there any difference when you are describing requirements for a monolith or a microservice? Which questions should be answered when you hear "Well, we'll put it in the cloud"?

As a person who is responsible for system architecture, I will try to answer these questions and describe my personal point of view about different ways of system analysis for different architecture patterns.
