For example, what if there is a lot of volatility in the amount of computing resources you need? This is a common issue for ecommerce vendors during the holidays, when there is a big spike in computing activity. There舗s also the matter of designing, tuning, or modifying the network to accommodate changing needs in usage, availability, security, or other factors. It turns out that for all the benefits of virtualization with respect to server operating systems and applications, there are still massive gains to be had by virtualizing the entire network infrastructure.
There is also the cost of power, which is a major financial consideration. All of these servers generate an enormous amount of heat, and the servers need to be kept cool. Interestingly, though, the temperatures that data centers are cooled to are more about human consideration than server consideration. It turns out that servers can operate efficiently at much higher temperatures than humans can tolerate over a sustained period of time. In fact, in some cases, robots are being used within the data centers left at higher temperatures (80+ F).

This concept of virtualizing the network leads us to the thrust of this book: software-defined networking (SDN).
