Welcome to your interview.
The question is on your right: Private vs Public Cloud Trade-offs. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How do you balance cost, performance, and security when designing an on-premises private cloud versus utilizing public cloud resources?
