When designing an architecture, many components need to be considered before deciding on the best solution. Let us take a look also the latency: Here the situation starts to be a little bit more complicated. MySQL Router is the one that has the higher latency no matter what. That allows it to go a bit further.

In case of a spike in traffic, you can automatically spin up more resources, often in a matter of seconds. Likewise, you can scale down when your application experiences decreased traffic. For example, as traffic increases, costs will too. This can dramatically decrease network latency and its effect on the end-user experience.

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.
