SDN: Software Defined Networks


Up until a few years ago, storage, computing, and network resources were intentionally kept physically and operationally separate from one another. Even the systems used to manage those resources were separated—often physically. Applications that interacted with any of these resources, such as an operational monitoring system, were also kept at arm’s length significantly involved access policies, systems, and access procedures all in the name of security. This is the way IT departments liked it. It was really only after the introduction of (and demand for) inexpensive computing power, storage, and net‐ working in data center environments that organizations were forced to bring these different elements together. It was a paradigm shift that also brought applications that manage and operate these resources much, much closer than ever before.
