why?

Sure, but my point is that 450m requests is just not a lot. Humans are bad at big numbers, and this number sounds like a scary amount of traffic, my point is that it is a very boring amount of traffic even on modest hardware.

I personally wouldn't stick it on a single VPS because we can do way better than that in terms of reliability, but the point stands that you don't need very much in terms of resources to serve this.
