VMware NSX
VMware's NSX network virtualization platform leverages virtual switches running in each hypervisor to create an SDN overlay. NSX is hardware-agnostic and aimed at improving network security and network management.
Earlier this year, VMware said NSX has 1,200 customers and an annual run rate of more than $600 million. To further boost NSX, VMware acquired Arkin, a Sunnyvale, Calif.-based startup that provides software to let organizations track traffic flows and security issues in virtualized and physical environments.
