3. When you scale down, you reduce parallelism
4. When you decouple a queue, each task inside it is treated independently and processed accordingly
6. Contain the logic, components, and libraries needed to process queue tasks
9. A waiter takes the order from the customer, the manager sends it to the chef. Same as the work queue manager
10. Grouping similar tasks together so they are processed as a collection

5. A waiter takes the order from the customer, the manager sends it to the chef. The customer is the external source
6. A waiter takes the order from the customer, the manager sends it to the chef. Who is the worker?
7. A waiter takes the order from the customer, the manager sends it to the chef. The waiter here is the ambassador container
8. Parallelism can help reduce backlog
