This is pretty interesting for capacity planning. I worked at a minor ecommerce company when Black Friday was still a big deal. In the month leading up to it, we went into code freeze and made sure all our systems can handle added load.

What Robinhood is facing is like that, but with no notice. It means they ~always need to be ready for a 4x(?) increase in load.

This is one of the problems that "the cloud" is supposed to solve. No need to keep infra up for that unicorn event, just to ensure that you can scale properly when it does happen.

Until you hit some kind of aggregation server that it's not trivial to scale out properly unless you take a completely different approach or that you may scale vertically up (but eventually you will hit the ceiling).
