If the answer you get to a software or coding problem is any variation of "just throw more computing power at it," including using "the cloud" (someone else's computers) instead of your own tiny server farm, the odds are pretty good you're either asking the wrong question or listening to a techbro.
While not perfect, growing your own tiny server farm can be rewarding.
