System design is, to some extent, about how information flows; by the way, what tool was used to draw the sequence diagram in the third point?😃 it looks cool

Exactly; understanding the flow of information is at the heart of system design.

Learning about system design in tidbits is a great idea to brush up on important concepts on how systems around us work

Amazing. This can also be extrapolated to explain that you don't always need microservice architecture. If your coffee shop is just starting out, and you have restrictions on cash to spend, then Cashier, Barista and all that is being done by just one person.

This would feel like standard Request-Response architecture.

Cashier takes your order, puts on Barista hat, brews your coffee, comes back and hand it over to you. Then he takes next order and so on.

Yes!

No need to over-engineer with microservices when a single-threaded flow gets the job done.
