Virtualization is technology that you can use to create virtual representations of servers, storage, networks, and other physical machines.
Virtual software mimics the functions of physical hardware to run multiple virtual machines simultaneously on a single physical machine.
Businesses use virtualization to use their hardware resources efficiently and get greater returns from their investment.
It also powers cloud computing services that help organizations manage infrastructure more efficiently. Network Virtualization (NV) refers to abstracting network resources that were traditionally delivered in hardware to software. NV can combine multiple physical networks to one virtual, software-based network, or it can divide one physical network into separate, independent virtual networks.
Network virtualization decouples network services from the underlying hardware and allows virtual provisioning of an entire network. It makes it possible to programmatically create, provision, and manage networks all in software, while continuing to leverage the underlying physical network as the packet-forwarding backplane. Physical network resources, such as switching, routing, firewalling, load balancing, virtual private networks (VPNs), and more, are pooled, delivered in software, and require only Internet Protocol (IP) packet forwarding from the underlying physical network.
