Up to a certain point, sure, you can vertically scale.
I work for a large CDN, with many thousands of servers pushing near line-rate out of our NICs... we certainly can't vertically scale that.
There is a limit to how much you can vertically scale.
Even for the things we CAN vertically scale, we need to be able to handle hardware failure and OS upgrades without taking any downtime, so you are going to need to be able to horizontally scale enough to handle that.

- hinkley 6y agoAnd the products that aren’t should hire out CDN networks to do that work for them instead of trying to roll their own.
- louwrentius 6y agoI agree with Jorams, this is not a common service. Most apps are things with an app server and db and most of all: they have a load that is easily handled by modest gear.
- cortesoft 6y agoI know, and I get that we aren’t the average tech company. I don’t think we are unique, though, and there are many engineers on here who work at all sorts of interesting places with non-standard workloads. I was just pointing out the reasons we can’t vertically scale.
