VMware NSX Data Center is the network virtualization and security platform that enables the virtual cloud network. It is a software-defined approach to networking that extends across data centers, clouds, endpoints, and edge locations. With NSX Data Center, network functions—including switching, routing, firewalling, and load balancing—are brought closer to the application and distributed across the environment. Similar to the operational model of virtual machines, networks can be provisioned and managed independent of underlying hardware.
