Linux advocates were outspoken about its superior scalability. NT owners don't necessarily agree. They point out that NT systems need to be scaled differently than Unix systems. Also, scaling large systems requires expertise as well as the right parts. For sites less high profile than these, though, getting the right staff, hired guns, or vendor support to plan and execute a rapidly scalable system could be a lot harder. Linux's architecture, on the other hand, resembles the Unix systems that large-scale sites have been using since the early '80s. Really good Unix developers and administrators are expensive, but if you're willing to pay for it, you can hire someone who has lived and breathed Unix since the '70s.
