Among colleges and universities that have made the move to software-defined servers and to software-defined storage, many find that a third option — software-defined networking ( #SDN ) — fits right in. The virtualization of these three pillars of the IT function into a software-defined data center (SDDC) offers high yield for less cost, making it a promising solution — think more agile, more efficient and cost-effective.
Indeed, as traditional networks have grown more complex, they risk becoming more hindrance than help. SDNs empower IT staffwith the same agility they find in virtualization, offering big shortcuts in the amount of time it takes to deliver services. Software updates replace manual configuration of hardware components. Staff also benefit from the increased control of centralized network management. What’s more, SDNs provide these advantages at a lower cost than traditional networks, thanks to increased automation and reduced equipment costs.
