Datacenters need automated network configuration, along with intelligence that will allow for switches and routers (both physical devices and virtual ones running on virtual machines inside of hypervisors) to be reconfigured on the fly, reacting to current network conditions. This, at its heart, is what software-defined networking is all about.
SDN is already happening at many large organizations, hyperscale datacenter operators, and cloud builders. There is more than one way to virtualize and automate the network, just as there is more than one way to virtualize a server and automate the provisioning and man- agement of virtual machines. The trick will be to find the approach best suited to a particular customer, and that is tough given that SDN technology is still new. As always, those that can’t wait wade in first.
