> Anything can be scalable using that definition. No, some things can't be, like badly architected monoliths, or databases. Especially with databases it's not a given, which is why for quite some time in the last years things like the "MongoDB is web scale" blew up and people started mindlessly asking "is it scalable" (which as you figured out, means very little for a lot of systems). I'm also pretty sure that your example scales worse than linearly, since you have to introduce multiple levels of management at some point. "scalable" = "can it be scaled", which is not a given for every system
