What is the best way to protect data? Concentrate it? Or spread it about? If you write your memoirs and lock them in a safe for future generations, then the house could burn down and they are gone forever. But if you publish and sell them, your memoirs could survive a world war. The Internet was built with resilience in mind. But it wasn't designed to address issues such as data privacy and sovereignty. With the rise of cloud computing, such issues are coming to the fore, and organisations are struggling with the problem of controlling where their data goes. Software-Defined Network (SDN) technology may provide the answer by allowing more control over routing. Industry-standard OpenFlow-enabled switches allow a network provider to reshape its network as a logical structure and to seek new ways to increase efficiency, offer better quality of service and rapidly explore new service opportunities, argues Dan Pitt of the Open Networking Foundation.
