Facebook and Google and Amazon do not use Cisco networking equipment, nor do they use Dell servers:<p><a href="http:&#x2F;&#x2F;www.wired.com&#x2F;2014&#x2F;11&#x2F;facebooks-new-data-center-bad-news-cisco&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.wired.com&#x2F;2014&#x2F;11&#x2F;facebooks-new-data-center-bad-n...</a><p>That&#x27;s basically the point of the article: These companies that actually had to get up to that kind of massive scale quickly discovered that the way hawked by these big expensive &quot;enterprise&quot; companies didn&#x27;t work. It was expensive and insufficient. So they&#x27;ve developed their own custom stuff (often built on open source; sometimes open sourced back out) that works a lot better while also being massively cheaper.<p>AWS isn&#x27;t just a bunch of Dell servers hooked up to EMC SANs and Cisco switches. The only people who still use that stuff are people who a) have a ton of money and a desire to spend it freely, plus b) don&#x27;t have really serious demands, which would mandate something better.<p>That&#x27;s not a good place to be.
