About a month ago I attended an analyst session with Michael Dell at VMWorld. During the event, Mr. Dell stated that he learned many years ago that when things are good for businesses, customers are going to do it, with or without the vendors’ help. He cited Dell’s initial resistance to virtualization as an example. Dell tried to stave off customers deploying server virtualization as it was bad for Dell but customers did it anyway, seriously hurting Dell’s position as a key technology supplier. Chuck Robbins made a similar statement shortly after he took the reigns at Cisco regarding software defined networking. He said something to the effect that Cisco’s job is to help customers through transitions, not get in the way, and that it would never again be dismissive of a technology that was beneficial to its customers.
