Lots of numbers that point to buying a fast server. Yes, it s a no-brainer that you ll need fast server hardware, but how fast is the big question.
Scalability is so important because of server cost.
The typical answer to a server that can t handle its user load is to add another box or replace the one you ve got. As you can see, in the real business world, you quickly skip over all the nitty-gritty questions of processor type, RAM and disk size. The scalability question puts you smack in the thick of things, deciding between processing architecture, base operating system, how many servers you ll need, and of what type. At this point, processor speed and RAM size are almost academic questions. It can t hurt to pile them on so buy until the budget weeps.
