Since then I've working on things that use several servers, things that use no servers with edge functions instead (which have servers, but still), and that use autoscaling across lots of servers.
No doubt some businesses need autoscaling but most don't. It definitely shouldn't be something you reach for before you actually anticipate a need for it.
