Your coffee shop doesn't use two-phase commit [asynchronous messaging architecture]

The real world is often asynchronous. Our daily lives consist of many coordinated but asynchronous interactions. This means that an asynchronous messaging architecture can often be a natural way to model these kinds of interactions. It also means that looking at daily life can help us solve our messaging problems. For example in this article we present how a coffee shop processes customer orders and compare it to the asynchronous processing model.
