The problem Because message-driven systems are asynchronous and run in multiple processes, debugging is naturally more complex than in a single-process application. Luckily, we can address these concerns with observability. ? Place order| B[Sales] B --> |2.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
