The new data center requires the networking not just of physical machines, but virtual ones as well. In a virtualized environment, multiple applications could live on multiple virtual machines on the same physical server. Traffic, as well as the applications themselves must be able to move between servers or between data centers. Virtual networking ensures that physical and virtual machines can be connected and managed by the network in the same way, providing consistent network and security policies for applications in motion or at rest.
