I agree with you. Many applications grow linerally or not at all. I personally run a couple hundred servers, but it's all VMware, chef and clustered. Frankly, most just sit at a stupid low load average, but I don't fuss it because the spare cycles aren't wasted and I can have hosts and storage fail with impunity. Many ways of doing it. Virtualization is basically all direct hardware access for the stuff that counts. But I digress. I am guilty of over building things. In part for fun. In part hubris. In part I like sleeping at night
