Among other things, we resell hardware and software. The basic idea is that customers can get a Dell, or Oracle server and a license for an Oracle database from us, when buying hosting. This saves them the trouble of dealing with multiple suppliers. The hardware and software business is just sort of a side thing, but we can generate crazy amounts of revenue by losing money on hardware. The idea is that we make the money back longterm on hosting. We never use revenue as a meaningful KPI, because we know that some years it will be inflated like crazy by hardware or software sales (which aren't profitable).
So I don't really see revenue as useful figure either, not without also knowing if you're profitable.
