Network virtualization is the use of logical network entities that utilize the underlying physical components of the network. The original network virtualization technology is the Virtual LAN (VLAN). This networking technology maps two disparate networks into a single, unified logical network entity. The VLAN is used in such a way that makes it appear as though everything was physically located together, though in reality, there may be remote connections defined. This same technology can be used to segment one contiguous network system. Applications or services in the server are given unique network identities, and routing within the server is handled along with networking protocols. The use of networking protocols effectively isolates the applications and services, often making them easier to monitor and manage.
