Your question is Design a High-Traffic System for Align. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me how you would design a system architecture for a high-traffic media-sharing application, such as Instagram, and explain how this approach could be applied to Align Technology's Invisalign and iTero platforms.
