Software-defined networking (SDN) is an approach to network virtualization that seeks to optimize network resources and quickly adapt networks to changing business needs, applications, and traffic. Software defined networking offers numerous benefits including on-demand provisioning, automated load balancing, streamlined physical infrastructure and the ability to scale network resources in lockstep with application and data needs. 

Having centralized SDN-control software manage the network can also help with network visibility and analytics because it has a view into the entire network environment.

SDN delivers a wide array of business benefits. Separation of the control and transport layers increases flexibility and accelerates time-to-market for new applications. The ability to respond more swiftly to issues and outages improves network availability.

One of the major benefits of an SDN implementation is that it allows software-based security tools to be installed and managed more easily on “east-west” server-to-server traffic within a data center. In an SDN environment, network administrators can more easily install virtual firewalls, encryption tools and network monitoring services to protect this intra-data center traffic.

SDN dramatically intensifies the processing ability of servers. Utilization rises, and storage is more condensed. The physical switches are replaced with radically simplified models, many of which do not carry brand names.
