The chief effect of the architectural difference is to shift the distribution of latency within the loop. Herein lies the source of our collective anxiety about front-end architectures: traversing networks is always fraught, but the costs to deliver client-side logic to cushion users from variable network latency remain stubbornly high.

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.

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.
