Welcome to your interview.
The question is on your right: Provision Multi-Tier with Terraform. 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.
Write a complete, syntactically correct Terraform configuration to provision a multi-tier cloud environment, including state file locking and backend configuration.
