VMware NSX is the network virtualization platform for the SDDC, delivering the operational model of a VM for entire networks. With NSX, network functions, including switching, routing, and firewalling, are embedded in the hypervisor and distributed across the environment. This effectively creates a network hypervisor that acts as a platform for virtual networks and services.
Like the operational model of VMs, virtual networks are programmatically provisioned and managed independently of underlying hardware. NSX reproduces the entire network model in software, enabling any network topology–from simple to complex multi-tiered networks–to be created and provisioned in seconds. Users can create multiple virtual networks with diverse requirements, leveraging a combination of the services offered via NSX to build inherently more secure environments.
