Welcome to your interview for the Solutions Architect role at Incedo.
The question is on your right: Traffic Spikes Under Cost and Latency Constraints. 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. You have three graded attempts to score 7/10 or better.
How would you design a system that can handle sudden traffic spikes while staying within strict cost and latency constraints for Incedo?
