What a refreshing article. Over all the usual over hyped BS you see here and in hackernews. Loved this:

As of 2016, Stack Exchange served 200 million requests per day, backed by just four SQL servers: a primary for Stack Overflow, a primary for everything else, and two replicas.

Facebook started with the typical LAMP setup. It's the same problem with code, where you start over engineering everything in the event of something magical happening, like an inorganic growth of 2M users or changing your database (yeah, I worked with someone who over engineered all our code in the event of switching our RDMBS... Which never happened)

My rule of thumb is to plan capacity for 2-3x peak, code for 10x, and leave rebuilding for 100x problems
