Many of today's services and applications, particularly those involving the cloud, would be impossible to run without Software Defined Networking. Software Defined Networking facilitates the movement of data between distributed locations, which is critical for cloud applications. Furthermore, Software Defined Networking allows for the rapid movement of workloads across a network. For example, by dividing a virtual network into sections, telecommunications providers can move customer services to less expensive servers or even the customer's own servers.
Service providers can use a virtual network infrastructure to move workloads from private to public cloud infrastructures as needed, and to instantly launch new customer services. Software Defined Networking also makes it easier for any network to flex and scale as network administrators add or remove virtual machines, regardless of whether those machines are virtual or physical. Software Defined Networking also makes it easier for any network to flex and scale as network administrators add or remove virtual machines, whether those machines are on-premises or in the cloud.
