Software Defined approach of Networking has gone beyond simply virtualization of network functions. By decoupling intelligence of the network from underlying hardware resources, it becomes more flexible, more programmable, more reliable. This paves the way for innovation, automation and further optimization of cost, quality and adaptability. With advent of Cloud services, IPv6, IoT, global-flexible workforce, it is critical to make this transition to Software Defined Networking.

Network is the backbone of all IT services. It is therefore natural for organizations to focus on its availability, quality and security. But majority of the efforts is spent on 'keeping the lights on' and so any major changes, innovations, improvement plans take backseat for operational and maintenance tasks. These operational tasks are repetitive and follow certain pattern making them prime candidate for Automation. This approach further leads to reduction on human dependency, making it error free, allowing an organization to focus on improvement and security of network.

IT services for an organization is going beyond the boundaries of Data Center. Consumers for the IT services like your customers, employees, vendors, partners etc. are also no longer location specific. Network should be available regardless with same quality and connectivity experience whether connecting from outside or inside. Security layers can be different, but resources accessibility should be defined by RBAC or location and not by network quality or type of device. That is true virtue of modern network, always secure, available everywhere, from any device.
