#Virtualization, arguably describable as "software-defined workloads," has become inextricably intertwined with both Software-Defined Storage ( #SDS ) and Software-Defined Networking ( #SDN ). The past decade had storage wars that redefined the IT landscape, and the upcoming one looks to see networking do the same. One term that will soon become commonplace for all virtualization administrators is microsegmentation. To understand microsegmentation, we first need to understand Virtual LANs ( #VLAN s). VLANs are a way to simulate separate physical networks without actually having to physically wire up separate networks. All devices on VLAN 10, for example, can communicate with one another. Those VLAN 10 devices cannot, however, communicate with devices on VLAN 20. As previously stated, VLANs were designed to simulate multiple physical networks atop a single physical infrastructure. Physical networks in this conceptualization usually consist of hundreds, thousands or even tens of thousands of devices in a single layer 2 switch fabric.
