If you like survey data, here’s an interesting fact for you. Every year since 2000, when I started surveying enterprises on the question, the most important factor driving investment and change in enterprise networks was the data center. It’s like the network is the tail of a big, fuzzy, maybe-largely-invisible dog, and it’s time we look at where that dog might be leading us.
Today’s virtual private networks (VPNs) evolved from the days when companies leased time-division-multiplexed (TDM) lines and connected their own routers. That approach focused companies on how to network sites, and they now think about networking people instead. But people are half the story; the other half is what the people are doing, which is accessing (increasingly via the cloud) data-center applications and databases.
