There is no question that wireless networks are taking over. Offices may still have Ethernet cables to each cubicle, but they usually go unused. Wi-Fi is the new LAN.

Virtualization is everywhere. We think of virtualization as beginning with PC-based servers then moving onto Linux boxes. But the origins are very different, going all the way back to 1968, when IBM invented virtualization with the release of the IBM System/360 Model 67 mainframe. We all know where it has gone since. PCs, storage and even networks are virtualized. Nowadays, enterprises and SMBs have a wealth of virtual devices and services they must manage and secure, with servers still leading the way.
