Network virtualization is the complete reproduction of a physical network in software. Virtual networks offer the same features and guarantees of a physical network, yet they deliver the operational benefits and hardware independence of virtualization—rapid provisioning, nondisruptive deployment, automated maintenance and support for both legacy and new applications.
Network virtualization presents logical networking devices and services—logical ports, switches, routers, firewalls, load balancers, VPNs and more—to connected workloads. Applications run on the virtual network exactly the same as if on a physical network.
You can create a highly scalable network fabric that provides greater levels operational efficiency and agility, faster provisioning, troubleshooting and cloning, with monitoring, QoS, and security all backed by VMware network virtualization software.
VMware NSX™ will be the world's leading network and security virtualization platform providing a full-service, programmatic and mobile virtual network for virtual machines, deployed on top of any general purpose IP network hardware.
The VMware NSX platform brings together the best of Nicira NVP and VMware vCloud® Networking and Security™ (vCNS) into one unified platform. VMware NSX exposes a complete suite of simplified logical networking elements and services including logical switches, routers, firewalls, load balancers, VPN, QoS, monitoring and security.
