Do you mean "server?". A large farm of them, probably. More likely a lot of little bits of a lot of them, rented from some service provider.
That depends. Does he want to be a news network guy, or an IT wonk? (Seriously: this gets back to the whole insource vs. outsource discussion -- if he knows news but not IT, then he should rent out as much expertise as he can, at least at first. Then if his business grows, when the inevitable happens and the service provider decides they don't want him as a customer anymore, he can consider hiring some clever IT folks and bringing that expertise -- and profit margin -- in house).
