Internet-based cloud platforms such as Amazon Web Services (AWS) and Microsoft Azure are indeed disrupting industries from the ground up. Public cloud services give startups that are unencumbered by legacy infrastructure, ways to develop and deploy new applications with unprecedented speed, flexibility, and efficiency. For many large enterprises, however, deploying new IT services in on-premise IT infrastructure is anything but fast, agile, and efficient. Fortunately, that is changing as traditional hardware-based networking is being "eaten" by software too. Indeed, Software Defined Networking (SDN) is an architecture that gives enterprises the power to radically simplify their network, making it easier to manage, and allowing applications to be deployed in minutes, rather than days.SDN has its roots in a number of research initiatives that sought to separate or abstract the control and management functionality of a networking device. The Internet Engineering Task Force, for example, created the ForCES (Forwarding and Control Element Separation) protocol in 2003 which separated the forwarding and control functionalities within a network device. Two years later a team at Stanford University launched the Clean Slate project with the idea of building a networking switch from scratch. Here the goal was to build a centralized control and management system that would look at the network as a whole in Software Defined Networking:Time to Unshackle the NetworkIn My OpinionBy Jennifer Artley, COO, BT AmericasJennifer Artley
