Micro-segmentation is one of the breakthrough benefits of the VMware NSX™ network virtualization platform. NSX creates a virtual network that is independent of the underlying IP network hardware. Administrators can programmatically create, provision, snapshot, delete and restore complex networks all in software. 

VMware describes micro-segmentation as the ability to “build security into your network’s DNA.” The best analogy is how plants can be engineered at the molecular or cellular levels to be pest and disease resistant.
