Ever wondered what really happens when you click "Place Order" on Amazon? In this short, we break down the classic system design problem of handling 6 background jobs — payment, inventory hold, order save, confirmation email, warehouse notification, and recommendation update.
We compare Option A (synchronous execution) vs Option B (async with background queues) and discuss the real engineering question: what MUST finish before showing "Order Placed," and what can run later safely? Drop your approach in the comments.
Perfect for system design interview prep, backend engineers, and anyone learning distributed systems.
