NSX-V is VMware’s network virtualization platform that
is completely integrated with vSphere. The NSX-V Firewall and the
Service Composer are key features of the NSX-V Manager. The NSX-V
firewall is a logical firewall that allows you to attach network
and security services to the virtual machines, and the Service Composer allows
you to group virtual machines and create policy to redirect traffic
to the VM-Series firewall (called the Palo Alto Networks NGFW service
on the NSX-V Manager).
