Not surprisingly, he advocates placing logical boundaries between data that needs to be kept separate such as software containers within phones to separate users personal data and applications from those used for business - tools his company makes.
Security also becomes less physical and logical boundaries and more behavioral, where anomalous behavior by individuals or applications raises security flags and sets of triggers set by risk profiles. "This is easier to do in a software-defined world," he says. VMware is promoting its concept of the software-defined virtual data center this week at VMworld.
Allowing personally owned devices in corporate networks is one thing, says Tucci, but there is a lot of shadow spending within businesses on unauthorized gear that could represent vulnerabilities.
This shift to using personal mobile devices is being called the post-PC era, but members of the panel disagree with that characterization. "The post PC era has been pretty good to PCs so far," says Dell, noting that the term has been applied since 1999 and PC sales have tripled since, although they are suffering now.
Maritz says a better way of looking at it is an era of multiple devices in which the device used is the one best suited to circumstances. "There are certain things you can only do on a big screen," he says, "like edit a PowerPoint."
Tucci says that any innovation and productivity gains in business require IT investments, but three quarters of IT budgets go toward maintaining the existing infrastructure. He says cost savings from use of virtual and cloud technology could be used to spark innovation and improve business processes.
But strictly in the IT realm, executives need to be willing to take chances on new technology that could boost productivity for their businesses of cloud infrastructure will help free up some of that budget, Georgens says. "The thing that gets you fired is when rivals create a competitive advantage when you, as CIO, said that type of move was impossible or too risky." Cloud was a technology many businesses were slow to latch onto sometimes to their disadvantage, he says.
